If you prefer you can replace all commands starting with a backslash below by their counterparts that start with an at-sign. Some commands have one or more arguments. Each argument has a certain range: If [square] brackets are used the argument is optional. Here is an alphabetically sorted list of all commands with references to their documentation: \secreflist \refitem cmda \\a \refitem cmdaddindex \\addindex \refitem cmdaddtogroup \\addtogroup \refitem cmdanchor \\anchor \refitem cmdarg \\arg \refitem cmdattention \\attention \refitem cmdauthor \\author \refitem cmdb \\b \refitem cmdbrief \\brief \refitem cmdbug \\bug \refitem cmdc \\c \refitem cmdcallgraph \\callgraph \refitem cmdcallergraph \\callergraph \refitem cmdcategory \\category \refitem cmdclass \\class \refitem cmdcode \\code \refitem cmdcond \\cond \refitem cmdcopybrief \\copybrief \refitem cmdcopydetails \\copydetails \refitem cmdcopydoc \\copydoc \refitem cmddate \\date \refitem cmddef \\def \refitem cmddefgroup \\defgroup \refitem cmddeprecated \\deprecated \refitem cmddetails \\details \refitem cmddir \\dir \refitem cmddontinclude \\dontinclude \refitem cmddot \\dot \refitem cmddotfile \\dotfile \refitem cmde \\e \refitem cmdelse \\else \refitem cmdelseif \\elseif \refitem cmdem \\em \refitem cmdendcode \\endcode \refitem cmdendcond \\endcond \refitem cmdenddot \\enddot \refitem cmdendhtmlonly \\endhtmlonly \refitem cmdendif \\endif \refitem cmdendlatexonly \\endlatexonly \refitem cmdendlink \\endlink \refitem cmdendmanonly \\endmanonly \refitem cmdendmsc \\endmsc \refitem cmdendverbatim \\endverbatim \refitem cmdendxmlonly \\endxmlonly \refitem cmdenum \\enum \refitem cmdexample \\example \refitem cmdexception \\exception \refitem cmdextends \\extends \refitem cmdfdollar \\f\$ \refitem cmdfbropen \\f[ \refitem cmdfbrclose \\f] \refitem cmdfcurlyopen \\f{ \refitem cmdfcurlyclose \\f} \refitem cmdfile \\file \refitem cmdfn \\fn \refitem cmdheaderfile \\headerfile \refitem cmdhideinitializer \\hideinitializer \refitem cmdhtmlinclude \\htmlinclude \refitem cmdhtmlonly \\htmlonly \refitem cmdif \\if \refitem cmdifnot \\ifnot \refitem cmdimage \\image \refitem cmdimplements \\implements \refitem cmdinclude \\include \refitem cmdincludelineno \\includelineno \refitem cmdingroup \\ingroup \refitem cmdinternal \\internal \refitem cmdinvariant \\invariant \refitem cmdinterface \\interface \refitem cmdlatexonly \\latexonly \refitem cmdli \\li \refitem cmdline \\line \refitem cmdlink \\link \refitem cmdmainpage \\mainpage \refitem cmdmanonly \\manonly \refitem cmdmemberof \\memberof \refitem cmdmsc \\msc \refitem cmdn \\n \refitem cmdname \\name \refitem cmdnamespace \\namespace \refitem cmdnosubgrouping \\nosubgrouping \refitem cmdnote \\note \refitem cmdoverload \\overload \refitem cmdp \\p \refitem cmdpackage \\package \refitem cmdpage \\page \refitem cmdpar \\par \refitem cmdparagraph \\paragraph \refitem cmdparam \\param \refitem cmdpost \\post \refitem cmdpre \\pre \refitem cmdprivate \\private \refitem cmdprivate \\privatesection \refitem cmdproperty \\property \refitem cmdprotected \\protected \refitem cmdprotected \\protectedsection \refitem cmdprotocol \\protocol \refitem cmdpublic \\public \refitem cmdpublic \\publicsection \refitem cmdref \\ref \refitem cmdrelates \\relates \refitem cmdrelatesalso \\relatesalso \refitem cmdremarks \\remarks \refitem cmdreturn \\return \refitem cmdretval \\retval \refitem cmdsa \\sa \refitem cmdsection \\section \refitem cmdsee \\see \refitem cmdshowinitializer \\showinitializer \refitem cmdsince \\since \refitem cmdskip \\skip \refitem cmdskipline \\skipline \refitem cmdstruct \\struct \refitem cmdsubpage \\subpage \refitem cmdsubsection \\subsection \refitem cmdsubsubsection \\subsubsection \refitem cmdtest \\test \refitem cmdthrow \\throw \refitem cmdtodo \\todo \refitem cmdtparam \\tparam \refitem cmdtypedef \\typedef \refitem cmdunion \\union \refitem cmduntil \\until \refitem cmdvar \\var \refitem cmdverbatim \\verbatim \refitem cmdverbinclude \\verbinclude \refitem cmdversion \\version \refitem cmdwarning \\warning \refitem cmdweakgroup \\weakgroup \refitem cmdxmlonly \\xmlonly \refitem cmdxrefitem \\xrefitem \refitem cmddollar \\\$ \refitem cmdat \\\@ \refitem cmdbackslash \\\\ \refitem cmdamp \\\& \refitem cmdtilde \\~ \refitem cmdlt \\\< \refitem cmdgt \\\> \refitem cmdhash \\\# \refitem cmdperc \\\% \refitem cmdquot \\\" \endsecreflist The following subsections provide a list of all commands that are recognized by doxygen.

\endhtmlonly

\htmlonly --- \endhtmlonly Structural indicators \htmlonly --- \endhtmlonly

\htmlonly
\endhtmlonly \section cmdaddtogroup \\addtogroup [(title)] \addindex \\addtogroup Defines a group just like \ref cmddefgroup "\\defgroup", but in contrast to that command using the same \ more than once will not result in a warning, but rather one group with a merged documentation and the first title found in any of the commands. The title is optional, so this command can also be used to add a number of entities to an existing group using \@{ and \@} like this: \verbatim /*! \addtogroup mygrp * Additional documentation for group `mygrp' * @{ */ /*! * A function */ void func1() { } /*! Another function */ void func2() { } /*! @} */ \endverbatim \sa page \ref grouping "Grouping", sections \ref cmddefgroup "\\defgroup", \ref cmdingroup "\\ingroup" and \ref cmdweakgroup "\\weakgroup".
\section cmdcallgraph \\callgraph \addindex \\callgraph When this command is put in a comment block of a function or method and \ref cfg_have_dot "HAVE_DOT" is set to YES, then doxygen will generate a call graph for that function (provided the implementation of the function or method calls other documented functions). The call graph will generated regardless of the value of \ref cfg_call_graph "CALL_GRAPH". \note The completeness (and correctness) of the call graph depends on the doxygen code parser which is not perfect.
\section cmdcallergraph \\callergraph \addindex \\callergraph When this command is put in a comment block of a function or method and \ref cfg_have_dot "HAVE_DOT" is set to YES, then doxygen will generate a caller graph for that function (provided the implementation of the function or method calls other documented functions). The caller graph will generated regardless of the value of \ref cfg_caller_graph "CALLER_GRAPH". \note The completeness (and correctness) of the caller graph depends on the doxygen code parser which is not perfect.
\section cmdcategory \\category [] [] \addindex \\category For Objective-C only: Indicates that a comment block contains documentation for a class category with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\section cmdclass \\class [] [] \addindex \\class Indicates that a comment block contains documentation for a class with name \. Optionally a header file and a header name can be specified. If the header-file is specified, a link to a verbatim copy of the header will be included in the HTML documentation. The \ argument can be used to overwrite the name of the link that is used in the class documentation to something other than \. This can be useful if the include name is not located on the default include path (like \). With the \ argument you can also specify how the include statement should look like, by adding either quotes or sharp brackets around the name. Sharp brackets are used if just the name is given. Note that the last two arguments can also specified using the \ref cmdheaderfile "\\headerfile" command. \par Example: \verbinclude class.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\section cmddef \\def \addindex \\def Indicates that a comment block contains documentation for a \c \#define macro. \par Example: \verbinclude define.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\section cmddefgroup \\defgroup (group title) \addindex \\defgroup Indicates that a comment block contains documentation for a \ref modules "group" of classes, files or namespaces. This can be used to categorize classes, files or namespaces, and document those categories. You can also use groups as members of other groups, thus building a hierarchy of groups. The \ argument should be a single-word identifier. \sa page \ref grouping "Grouping", sections \ref cmdingroup "\\ingroup", \ref cmdaddtogroup "\\addtogroup", \ref cmdweakgroup "\\weakgroup".
\section cmddir \\dir [] \addindex \\dir Indicates that a comment block contains documentation for a directory. The "path fragment" argument should include the directory name and enough of the path to be unique w.r.t. the other directories in the project. The \ref cfg_show_dirs "SHOW_DIRECTORIES" option determines whether or not the directory information is shown and the \ref cfg_strip_from_path "STRIP_FROM_PATH" option determines what is stripped from the full path before it appears in the output.
\section cmdenum \\enum \addindex \\enum Indicates that a comment block contains documentation for an enumeration, with name \. If the enum is a member of a class and the documentation block is located outside the class definition, the scope of the class should be specified as well. If a comment block is located directly in front of an enum declaration, the \\enum comment may be omitted. \par Note: The type of an anonymous enum cannot be documented, but the values of an anonymous enum can. \par Example: \verbinclude enum.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\section cmdexample \\example \addindex \\example Indicates that a comment block contains documentation for a source code example. The name of the source file is \. The text of this file will be included in the documentation, just after the documentation contained in the comment block. All examples are placed in a list. The source code is scanned for documented members and classes. If any are found, the names are cross-referenced with the documentation. Source files or directories can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file. If \ itself is not unique for the set of example files specified by the \ref cfg_example_path "EXAMPLE_PATH" tag, you can include part of the absolute path to disambiguate it. If more that one source file is needed for the example, the \\include command can be used. \par Example: \verbinclude example.cpp Where the example file \c example_test.cpp looks as follows: \verbinclude example_test.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa section \ref cmdinclude "\\include".
\section cmdextends \\extends \addindex \\extends This command can be used to manually indicate an inheritance relation, when the programming language does not support this concept natively (e.g. C). The file \c manual.c in the example directory shows how to use this command. \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa section \ref cmdimplements "\\implements" and section \ref cmdmemberof "\\memberof"
\section cmdfile \\file [] \addindex \\file Indicates that a comment block contains documentation for a source or header file with name \. The file name may include (part of) the path if the file-name alone is not unique. If the file name is omitted (i.e. the line after \\file is left blank) then the documentation block that contains the \\file command will belong to the file it is located in. \par Important: The documentation of global functions, variables, typedefs, and enums will only be included in the output if the file they are in is documented as well. \par Example: \verbinclude file.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \note In the above example \ref cfg_javadoc_autobrief "JAVADOC_AUTOBRIEF" has been set to YES in the configuration file.
\section cmdfn \\fn (function declaration) \addindex \\fn Indicates that a comment block contains documentation for a function (either global or as a member of a class). This command is \em only needed if a comment block is \e not placed in front (or behind) the function declaration or definition. If your comment block \e is in front of the function declaration or definition this command can (and to avoid redundancy should) be omitted. A full function declaration including arguments should be specified after the \\fn command on a \e single line, since the argument ends at the end of the line! \warning Do not use this command if it is not absolutely needed, since it will lead to duplication of information and thus to errors. \par Example: \verbinclude func.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa section \ref cmdvar "\\var" and \ref cmdtypedef "\\typedef".
\section cmdheaderfile \\headerfile [] \addindex \\headerfile Intended to be used for class, struct, or union documentation, where the documentation is in front of the definition. The arguments of this command are the same as the second and third argument of \ref cmdclass "\\cmdclass". The header-file name refers to the file that should by included by the application to obtain the definition of the class, struct, or union. The \ argument can be used to overwrite the name of the link that is used in the class documentation to something other than \. This can be useful if the include name is not located on the default include path (like \). With the \ argument you can also specify how the include statement should look like, by adding either quotes or sharp brackets around the name. Sharp brackets are used if just the name is given.
\section cmdhideinitializer \\hideinitializer \addindex \\hideinitializer By default the value of a define and the initializer of a variable are displayed unless they are longer than 30 lines. By putting this command in a comment block of a define or variable, the initializer is always hidden. \sa section \ref cmdshowinitializer "\\showinitializer".
\section cmdimplements \\implements \addindex \\implements This command can be used to manually indicate an inheritance relation, when the programming language does not support this concept natively (e.g. C). The file \c manual.c in the example directory shows how to use this command. \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa section \ref cmdextends "\\extends" and section \ref cmdmemberof "\\memberof"
\section cmdingroup \\ingroup ( [ ]) \addindex \\ingroup If the \\ingroup command is placed in a comment block of a class, file or namespace, then it will be added to the group or groups identified by \. \sa page \ref grouping "Grouping", sections \ref cmddefgroup "\\defgroup", \ref cmdaddtogroup "\\addtogroup" and \ref cmdweakgroup "\\weakgroup"
\section cmdinterface \\interface [] [] \addindex \\interface Indicates that a comment block contains documentation for an interface with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\section cmdinternal \\internal \addindex \\internal This command writes the message `For internal use only' to the output and all text \e after an \c \\internal command until the end of the comment block or the end of the section (whichever comes first) is marked as "internal". If the \\internal command is put inside a section (see for example \ref cmdsection "\\section") all subsection after the command are considered to be internal as well. Only a new section at the same level will be visible again. You can use \ref cfg_internal_docs "INTERNAL_DOCS" in the config file to show or hide the internal documentation.
\section cmdmainpage \\mainpage [(title)] \addindex \\mainpage If the \\mainpage command is placed in a comment block the block is used to customize the index page (in HTML) or the first chapter (in \f$\mbox{\LaTeX}\f$). The title argument is optional and replaces the default title that doxygen normally generates. If you do not want any title you can specify \c notitle as the argument of \\mainpage. Here is an example: \verbatim /*! \mainpage My Personal Index Page * * \section intro_sec Introduction * * This is the introduction. * * \section install_sec Installation * * \subsection step1 Step 1: Opening the box * * etc... */ \endverbatim You can refer to the main page using \\ref index (if the treeview is disabled, otherwise you should use \\ref main). \sa section \ref cmdsection "\\section", section \ref cmdsubsection "\\subsection" and section \ref cmdpage "\\page".
\section cmdmemberof \\memberof \addindex \\memberof This command make a function a member of a class in a similar way as \ref cmdrelates "\\relates" does, only with this command the function is represented as a real member of the class. This can be useful when the programming language does not support the concept of member functions natively (e.g. C). It is also possible to use this command together with \ref cmdpublic "\\public", \ref cmdprotected "\\protected" or \ref cmdprivate "\\private". The file \c manual.c in the example directory shows how to use this command. \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa sections \ref cmdextends "\\extends", \ref cmdimplements "\\implements", \ref cmdpublic "\\public", \ref cmdprotected "\\protected" and \ref cmdprivate "\\private".
\section cmdname \\name (header) \addindex \\name This command turns a comment block into a header definition of a member group. The comment block should be followed by a //\@{ ... //\@} block containing the members of the group. See section \ref memgroup for an example.
\section cmdnamespace \\namespace \addindex \\namespace Indicates that a comment block contains documentation for a namespace with name \.
\section cmdnosubgrouping \\nosubgrouping \addindex \\nosubgrouping This command can be put in the documentation of a class. It can be used in combination with member grouping to avoid that doxygen puts a member group as a subgroup of a Public/Protected/Private/... section.
\section cmdoverload \\overload [(function declaration)] \addindex \\overload This command can be used to generate the following standard text for an overloaded member function: `This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.' If the documentation for the overloaded member function is not located in front of the function declaration or definition, the optional argument should be used to specify the correct function. Any other documentation that is inside the documentation block will by appended after the generated message. \par Note 1: You are responsible that there is indeed an earlier documented member that is overloaded by this one. To prevent that document reorders the documentation you should set \ref cfg_sort_member_docs "SORT_MEMBER_DOCS" to NO in this case. \par Note 2: The \\overload command does not work inside a one-line comment. \par Example: \verbinclude examples/overload.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\section cmdpackage \\package \addindex \\package Indicates that a comment block contains documentation for a Java package with name \.
\section cmdpage \\page (title) \addindex \\page Indicates that a comment block contains a piece of documentation that is not directly related to one specific class, file or member. The HTML generator creates a page containing the documentation. The \f$\mbox{\LaTeX}\f$ generator starts a new section in the chapter `Page documentation'. \par Example: \verbinclude page.doc \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \par Note: The \ argument consists of a combination of letters and number digits. If you wish to use upper case letters (e.g. \c MYPAGE1), or mixed case letters (e.g. \c MyPage1) in the \ argument, you should set \c CASE_SENSE_NAMES to \c YES. However, this is advisable only if your file system is case sensitive. Otherwise (and for better portability) you should use all lower case letters (e.g. \c mypage1) for \ in all references to the page. \sa section \ref cmdsection "\\section", section \ref cmdsubsection "\\subsection", and section \ref cmdref "\\ref".
\section cmdprivate \\private \addindex \\private \addindex \\privatesection Indicates that the member documented in the comment block is private, i.e., should only be accessed by other members in the same class. Note that Doxygen automatically detects the protection level of members in object-oriented languages. This command is intended for use only when the language does not support the concept of protection level natively (e.g. C, PHP 4). For starting a section of private members, in a way similar to the "private:" class marker in C++, use \\privatesection. \sa sections \ref cmdmemberof "\\memberof", \ref cmdpublic "\\public", and \ref cmdprotected "\\protected".
\section cmdproperty \\property (qualified property name) \addindex \\property Indicates that a comment block contains documentation for a property (either global or as a member of a class). This command is equivalent to \\var and \\fn. \sa section \ref cmdfn "\\fn" and \ref cmdvar "\\var".
\section cmdprotected \\protected \addindex \\protected \addindex \\protectedsection Indicates that the member documented in the comment block is protected, i.e., should only be accessed by other members in the same or derived classes. Note that Doxygen automatically detects the protection level of members in object-oriented languages. This command is intended for use only when the language does not support the concept of protection level natively (e.g. C, PHP 4). For starting a section of protected members, in a way similar to the "protected:" class marker in C++, use \\protectedsection. \sa sections \ref cmdmemberof "\\memberof", \ref cmdpublic "\\public", and \ref cmdprivate "\\private".
\section cmdprotocol \\protocol [] [] \addindex \\protocol Indicates that a comment block contains documentation for a protocol in Objective-C with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\section cmdpublic \\public \addindex \\public \addindex \\publicsection Indicates that the member documented in the comment block is public, i.e., can be accessed by any other class or function. Note that Doxygen automatically detects the protection level of members in object-oriented languages. This command is intended for use only when the language does not support the concept of protection level natively (e.g. C, PHP 4). For starting a section of public members, in a way similar to the "public:" class marker in C++, use \\publicsection. \sa sections \ref cmdmemberof "\\memberof", \ref cmdprotected "\\protected" and \ref cmdprivate "\\private".
\section cmdrelates \\relates \addindex \\relates This command can be used in the documentation of a non-member function \. It puts the function inside the `related function' section of the class documentation. This command is useful for documenting non-friend functions that are nevertheless strongly coupled to a certain class. It prevents the need of having to document a file, but only works for functions. \par Example: \verbinclude relates.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\section cmdrelatesalso \\relatesalso \addindex \\relatesalso This command can be used in the documentation of a non-member function \. It puts the function both inside the `related function' section of the class documentation as well as leaving its normal file documentation location. This command is useful for documenting non-friend functions that are nevertheless strongly coupled to a certain class. It only works for functions.
\section cmdshowinitializer \\showinitializer \addindex \\showinitializer By default the value of a define and the initializer of a variable are only displayed if they are less than 30 lines long. By putting this command in a comment block of a define or variable, the initializer is shown unconditionally. \sa section \ref cmdhideinitializer "\\hideinitializer".
\section cmdstruct \\struct [] [] \addindex \\struct Indicates that a comment block contains documentation for a struct with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\section cmdtypedef \\typedef (typedef declaration) \addindex \\typedef Indicates that a comment block contains documentation for a typedef (either global or as a member of a class). This command is equivalent to \\var and \\fn. \sa section \ref cmdfn "\\fn" and \ref cmdvar "\\var".
\section cmdunion \\union [] [] \addindex \\union Indicates that a comment block contains documentation for a union with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\section cmdvar \\var (variable declaration) \addindex \\var Indicates that a comment block contains documentation for a variable or enum value (either global or as a member of a class). This command is equivalent to \\typedef and \\fn. \sa section \ref cmdfn "\\fn" and \ref cmdtypedef "\\typedef".
\section cmdweakgroup \\weakgroup [(title)] \addindex \\addtogroup Can be used exactly like \ref cmdaddtogroup "\\addtogroup", but has a lower priority when it comes to resolving conflicting grouping definitions. \sa page \ref grouping "Grouping" and \ref cmdaddtogroup "\\addtogroup".

\section cmdattention \\attention { attention text } \addindex \\attention Starts a paragraph where a message that needs attention may be entered. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\attention commands will be joined into a single paragraph. The \\attention command ends when a blank line or some other sectioning command is encountered.
\section cmdauthor \\author { list of authors } \addindex \\author Starts a paragraph where one or more author names may be entered. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\author commands will be joined into a single paragraph. Each author description will start a new line. Alternatively, one \\author command may mention several authors. The \\author command ends when a blank line or some other sectioning command is encountered. \par Example: \verbinclude author.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\section cmdbrief \\brief {brief description} \addindex \\brief Starts a paragraph that serves as a brief description. For classes and files the brief description will be used in lists and at the start of the documentation page. For class and file members, the brief description will be placed at the declaration of the member and prepended to the detailed description. A brief description may span several lines (although it is advised to keep it brief!). A brief description ends when a blank line or another sectioning command is encountered. If multiple \\brief commands are present they will be joined. See section \ref cmdauthor "\\author" for an example. Synonymous to \\short.
\section cmdbug \\bug { bug description } \addindex \\bug Starts a paragraph where one or more bugs may be reported. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\bug commands will be joined into a single paragraph. Each bug description will start on a new line. Alternatively, one \\bug command may mention several bugs. The \\bug command ends when a blank line or some other sectioning command is encountered. See section \ref cmdauthor "\\author" for an example.
\section cmdcond \\cond [] \addindex \\cond Starts a conditional section that ends with a corresponding \ref cmdendcond "\\endcond" command, which is typically found in another comment block. The main purpose of this pair of commands is to (conditionally) exclude part of a file from processing (in older version of doxygen this could only be achieved using C preprocessor commands). The section between \\cond and \\endcond commands can be included by adding its section label to the \ref cfg_enabled_sections "ENABLED_SECTIONS" configuration option. If the section label is omitted, the section will be excluded from processing unconditionally. For conditional sections within a comment block one should use a \ref cmdif "\\if" ... \ref cmdendif "\\endif" block. Conditional sections can be nested. In this case a nested section will only be shown if it and its containing section are included. Here is an example showing the commands in action: \verbatim /** An interface */ class Intf { public: /** A method */ virtual void func() = 0; /// @cond TEST /** A method used for testing */ virtual void test() = 0; /// @endcond }; /// @cond DEV /* * The implementation of the interface */ class Implementation : public Intf { public: void func(); /// @cond TEST void test(); /// @endcond /// @cond /** This method is obsolete and does * not show up in the documentation. */ void obsolete(); /// @endcond }; /// @endcond \endverbatim The output will be different depending on whether or not \c ENABLED_SECTIONS contains \c TEST, or \c DEV
\section cmddate \\date { date description } \addindex \\date Starts a paragraph where one or more dates may be entered. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\date commands will be joined into a single paragraph. Each date description will start on a new line. Alternatively, one \\date command may mention several dates. The \\date command ends when a blank line or some other sectioning command is encountered. See section \ref cmdauthor "\\author" for an example.
\section cmddeprecated \\deprecated { description } \addindex \\deprecated Starts a paragraph indicating that this documentation block belongs to a deprecated entity. Can be used to describe alternatives, expected life span, etc.
\section cmddetails \\details {detailed decription} \addindex \\details Just like \ref cmdbrief "\\brief" starts a brief description, \\details starts the detailed description. You can also start a new paragraph (blank line) then the \\details command is not needed.
\section cmdelse \\else \addindex \\else Starts a conditional section if the previous conditional section was not enabled. The previous section should have been started with a \c \\if, \c \\ifnot, or \c \\elseif command. \sa \ref cmdif "\\if", \ref cmdifnot "\\ifnot", \ref cmdelseif "\\elseif", \ref cmdendif "\\endif."
\section cmdelseif \\elseif \addindex \\elseif Starts a conditional documentation section if the previous section was not enabled. A conditional section is disabled by default. To enable it you must put the section-label after the \ref cfg_enabled_sections "ENABLED_SECTIONS" tag in the configuration file. Conditional blocks can be nested. A nested section is only enabled if all enclosing sections are enabled as well. \sa sections \ref cmdendif "\\endif", \ref cmdifnot "\\ifnot", \ref cmdelse "\\else", and \ref cmdelseif "\\elseif".
\section cmdendcond \\endcond \addindex \\endcond Ends a conditional section that was started by \ref cmdcond "\\cond". \sa \ref cmdcond "\\cond".
\section cmdendif \\endif \addindex \\endif Ends a conditional section that was started by \c \\if or \c \\ifnot For each \c \\if or \c \\ifnot one and only one matching \c \\endif must follow. \sa \ref cmdif "\\if", and \ref cmdifnot "\\ifnot".
\section cmdexception \\exception { exception description } \addindex \\exception Starts an exception description for an exception object with name \. Followed by a description of the exception. The existence of the exception object is not checked. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\exception commands will be joined into a single paragraph. Each parameter description will start on a new line. The \\exception description ends when a blank line or some other sectioning command is encountered. See section \ref cmdfn "\\fn" for an example. \par Note: the tag \\exceptions is a synonym for this tag.
\section cmdif \\if \addindex \\if Starts a conditional documentation section. The section ends with a matching \c \\endif command. A conditional section is disabled by default. To enable it you must put the section-label after the \ref cfg_enabled_sections "ENABLED_SECTIONS" tag in the configuration file. Conditional blocks can be nested. A nested section is only enabled if all enclosing sections are enabled as well. \par Example: \verbatim /*! Unconditionally shown documentation. * \if Cond1 * Only included if Cond1 is set. * \endif * \if Cond2 * Only included if Cond2 is set. * \if Cond3 * Only included if Cond2 and Cond3 are set. * \endif * More text. * \endif * Unconditional text. */ \endverbatim You can also use conditional commands inside aliases. To document a class in two languages you could for instance use: \par Example 2: \verbatim /*! \english * This is English. * \endenglish * \dutch * Dit is Nederlands. * \enddutch */ class Example { }; \endverbatim Where the following aliases are defined in the configuration file: \verbatim ALIASES = "english=\if english" \ "endenglish=\endif" \ "dutch=\if dutch" \ "enddutch=\endif" \endverbatim and \c ENABLED_SECTIONS can be used to enable either \c english or \c dutch. \sa sections \ref cmdendif "\\endif", \ref cmdifnot "\\ifnot", \ref cmdelse "\\else", and \ref cmdelseif "\\elseif".
\section cmdifnot \\ifnot \addindex \\ifnot Starts a conditional documentation section. The section ends with a matching \c \\endif command. This conditional section is enabled by default. To disable it you must put the section-label after the \ref cfg_enabled_sections "ENABLED_SECTIONS" tag in the configuration file. \sa sections \ref cmdendif "\\endif", \ref cmdif "\\if", \ref cmdelse "\\else", and \ref cmdelseif "\\elseif".
\section cmdinvariant \\invariant { description of invariant } \addindex \\invariant Starts a paragraph where the invariant of an entity can be described. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\invariant commands will be joined into a single paragraph. Each invariant description will start on a new line. Alternatively, one \\invariant command may mention several invariants. The \\invariant command ends when a blank line or some other sectioning command is encountered.
\section cmdnote \\note { text } \addindex \\note Starts a paragraph where a note can be entered. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\note commands will be joined into a single paragraph. Each note description will start on a new line. Alternatively, one \\note command may mention several notes. The \\note command ends when a blank line or some other sectioning command is encountered. See section \ref cmdpar "\\par" for an example.
\section cmdpar \\par [(paragraph title)] { paragraph } \addindex \\par If a paragraph title is given this command starts a paragraph with a user defined heading. The heading extends until the end of the line. The paragraph following the command will be indented. If no paragraph title is given this command will start a new paragraph. This will also work inside other paragraph commands (like \\param or \\warning) without ending the that command. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. The \\par command ends when a blank line or some other sectioning command is encountered. \par Example: \verbinclude par.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\section cmdparam \\param { parameter description } \addindex \\param Starts a parameter description for a function parameter with name \, followed by a description of the parameter. The existence of the parameter is checked and a warning is given if the documentation of this (or any other) parameter is missing or not present in the function declaration or definition. The \\param command has an optional attribute specifying the direction of the attribute. Possible values are "in" and "out". Here is an example for the function memcpy: \code /*! * Copies bytes from a source memory area to a destination memory area, * where both areas may not overlap. * @param[out] dest The memory area to copy to. * @param[in] src The memory area to copy from. * @param[in] n The number of bytes to copy */ void memcpy(void *dest, const void *src, size_t n); \endcode If a parameter is both input and output, use [in,out] as an attribute. The parameter description is a paragraph with no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\param commands will be joined into a single paragraph. Each parameter description will start on a new line. The \\param description ends when a blank line or some other sectioning command is encountered. See section \ref cmdfn "\\fn" for an example.
\section cmdtparam \\tparam { description } \addindex \\tparam Starts a template parameters for a class or function template parameter with name \, followed by a description of the template parameter. Otherwise similar to \ref cmdparam "\\cmdparam".
\section cmdpost \\post { description of the postcondition } \addindex \\post Starts a paragraph where the postcondition of an entity can be described. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\post commands will be joined into a single paragraph. Each postcondition will start on a new line. Alternatively, one \\post command may mention several postconditions. The \\post command ends when a blank line or some other sectioning command is encountered.
\section cmdpre \\pre { description of the precondition } \addindex \\pre Starts a paragraph where the precondition of an entity can be described. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\pre commands will be joined into a single paragraph.

The \\pre command ends when a blank line or some other sectioning command is encountered.
\section cmdremarks \\remarks { remark text } \addindex \\remarks Starts a paragraph where one or more remarks may be entered. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\remark commands will be joined into a single paragraph. Each remark will start on a new line. Alternatively, one \\remark command may mention several remarks. The \\remark command ends when a blank line or some other sectioning command is encountered.
\section cmdreturn \\return { description of the return value } \addindex \\return Starts a return value description for a function. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\return commands will be joined into a single paragraph. The \\return description ends when a blank line or some other sectioning command is encountered. See section \ref cmdfn "\\fn" for an example.
\section cmdretval \\retval { description } \addindex \\retval Starts a return value description for a function with name \. Followed by a description of the return value. The text of the paragraph that forms the description has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\retval commands will be joined into a single paragraph. Each return value description will start on a new line. The \\retval description ends when a blank line or some other sectioning command is encountered.
\section cmdsa \\sa { references } \addindex \\sa Starts a paragraph where one or more cross-references to classes, functions, methods, variables, files or URL may be specified. Two names joined by either :: or \# are understood as referring to a class and one of its members. One of several overloaded methods or constructors may be selected by including a parenthesized list of argument types after the method name. Synonymous to \\see. \sa section \ref autolink "autolink" for information on how to create links to objects.
\section cmdsee \\see { references } \addindex \\see Equivalent to \ref cmdsa "\\sa". Introduced for compatibility with Javadoc.
\section cmdsince \\since { text } \addindex \\since This tag can be used to specify since when (version or time) an entity is available. The paragraph that follows \\since does not have any special internal structure. All visual enhancement commands may be used inside the paragraph. The \\since description ends when a blank line or some other sectioning command is encountered.
\section cmdtest \\test { paragraph describing a test case } \addindex \\test Starts a paragraph where a test case can be described. The description will also add the test case to a separate test list. The two instances of the description will be cross-referenced. Each test case in the test list will be preceded by a header that indicates the origin of the test case.
\section cmdthrow \\throw { exception description } \addindex \\throw Synonymous to \\exception (see section \ref cmdexception "\\exception"). \par Note: the tag \\throws is a synonym for this tag.
\section cmdtodo \\todo { paragraph describing what is to be done } \addindex \\todo Starts a paragraph where a TODO item is described. The description will also add an item to a separate TODO list. The two instances of the description will be cross-referenced. Each item in the TODO list will be preceded by a header that indicates the origin of the item.
\section cmdversion \\version { version number } \addindex \\version Starts a paragraph where one or more version strings may be entered. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\version commands will be joined into a single paragraph. Each version description will start on a new line. Alternatively, one \\version command may mention several version strings. The \\version command ends when a blank line or some other sectioning command is encountered. See section \ref cmdauthor "\\author" for an example.
\section cmdwarning \\warning { warning message } \addindex \\warning Starts a paragraph where one or more warning messages may be entered. The paragraph will be indented. The text of the paragraph has no special internal structure. All visual enhancement commands may be used inside the paragraph. Multiple adjacent \\warning commands will be joined into a single paragraph. Each warning description will start on a new line. Alternatively, one \\warning command may mention several warnings. The \\warning command ends when a blank line or some other sectioning command is encountered. See section \ref cmdauthor "\\author" for an example.
\section cmdxrefitem \\xrefitem "(heading)" "(list title)" {text} \addindex \\xrefitem This command is a generalization of commands such as \ref cmdtodo "\\todo" and \ref cmdbug "\\bug". It can be used to create user-defined text sections which are automatically cross-referenced between the place of occurrence and a related page, which will be generated. On the related page all sections of the same type will be collected. The first argument \ is a identifier uniquely representing the type of the section. The second argument is a quoted string representing the heading of the section under which text passed as the forth argument is put. The third argument (list title) is used as the title for the related page containing all items with the same key. The keys "todo", "test", "bug", and "deprecated" are predefined. To get an idea on how to use the \\xrefitem command and what its effect is, consider the todo list, which (for English output) can be seen an alias for the command \verbatim \xrefitem todo "Todo" "Todo List" \endverbatim Since it is very tedious and error-prone to repeat the first three parameters of the command for each section, the command is meant to be used in combination with the \ref cfg_aliases "ALIASES" option in the configuration file. To define a new command \\reminder, for instance, one should add the following line to the configuration file: \verbatim ALIASES += "reminder=\xrefitem reminders \"Reminder\" \"Reminders\"" \endverbatim Note the use of escaped quotes for the second and third argument of the \\xrefitem command.

\section cmdaddindex \\addindex (text) \addindex \\addindex This command adds (text) to the \f$\mbox{\LaTeX}\f$ index.
\section cmdanchor \\anchor \addindex \\anchor This command places an invisible, named anchor into the documentation to which you can refer with the \\ref command. \note Anchors can currently only be put into a comment block that is marked as a page (using \ref cmdpage "\\page") or mainpage (\ref cmdmainpage "\\mainpage"). \sa section \ref cmdref "\\ref".
\section cmdendlink \\endlink \addindex \\endlink This command ends a link that is started with the \\link command. \sa section \ref cmdlink "\\link".
\section cmdlink \\link \addindex \\link The links that are automatically generated by doxygen always have the name of the object they point to as link-text. The \\link command can be used to create a link to an object (a file, class, or member) with a user specified link-text. The link command should end with an \\endlink command. All text between the \\link and \\endlink commands serves as text for a link to the \ specified as the first argument of \\link. See section \ref autolink "autolink" for more information on automatically generated links and valid link-objects.
\section cmdref \\ref ["(text)"] \addindex \\ref Creates a reference to a named section, subsection, page or anchor. For HTML documentation the reference command will generate a link to the section. For a sections or subsections the title of the section will be used as the text of the link. For anchor the optional text between quotes will be used or \ if no text is specified. For \f$\mbox{\LaTeX}\f$ documentation the reference command will generate a section number for sections or the text followed by a page number if \ refers to an anchor. \sa Section \ref cmdpage "\\page" for an example of the \\ref command.
\section cmdsubpage \\subpage ["(text)"] \addindex \\subpage This command can be used to create a hierarchy of pages. The same structure can be made using the \ref cmddefgroup "\\defgroup" and \ref cmdingroup "\\ingroup" commands, but for pages the \\subpage command is often more convenient. The main page (see \ref cmdmainpage "\\mainpage") is typically the root of hierarchy. This command behaves similar as \ref cmdref "\\ref" in the sense that it creates a reference to a page labeled \ with the optional link text as specified in the second argument. It differs from the \\ref command in that it only works for pages, and creates a parent-child relation between pages, where the child page (or sub page) is identified by label \. See the \ref cmdsection "\\section" and \ref cmdsubsection "\\subsection" commands if you want to add structure without creating multiple pages. \note Each page can be the sub page of only one other page and no cyclic relations are allowed, i.e. the page hierarchy must have a tree structure. Here is an example: \verbatim /*! \mainpage A simple manual Some general info. This manual is divided in the following sections: - \subpage intro - \subpage advanced "Advanced usage" */ //----------------------------------------------------------- /*! \page intro Introduction This page introduces the user to the topic. Now you can proceed to the \ref advanced "advanced section". */ //----------------------------------------------------------- /*! \page advanced Advanced Usage This page is for advanced users. Make sure you have first read \ref intro "the introduction". */ \endverbatim
\section cmdsection \\section (section title) \addindex \\section Creates a section with name \. The title of the section should be specified as the second argument of the \\section command. \warning This command only works inside related page documentation and \e not in other documentation blocks!
\section cmdsubsection \\subsection (subsection title) \addindex \\subsection Creates a subsection with name \. The title of the subsection should be specified as the second argument of the \\subsection command. \warning This command only works inside a section of a related page documentation block and \e not in other documentation blocks! \sa Section \ref cmdpage "\\page" for an example of the \ref cmdsubsection "\\subsection" command.
\section cmdsubsubsection \\subsubsection (subsubsection title) \addindex \\subsubsection Creates a subsubsection with name \. The title of the subsubsection should be specified as the second argument of the \\subsubsection command. \warning This command only works inside a subsection of a related page documentation block and \e not in other documentation blocks! \sa Section \ref cmdpage "\\page" for an example of the \ref cmdsubsubsection "\\subsubsection" command.
\section cmdparagraph \\paragraph (paragraph title) \addindex \\paragraph Creates a named paragraph with name \. The title of the paragraph should be specified as the second argument of the \\paragraph command. \warning This command only works inside a subsubsection of a related page documentation block and \e not in other documentation blocks! \sa Section \ref cmdpage "\\page" for an example of the \ref cmdparagraph "\\paragraph" command.

\section cmddontinclude \\dontinclude \addindex \\dontinclude This command can be used to parse a source file without actually verbatim including it in the documentation (as the \\include command does). This is useful if you want to divide the source file into smaller pieces and add documentation between the pieces. Source files or directories can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file. The class and member declarations and definitions inside the code fragment are `remembered' during the parsing of the comment block that contained the \\dontinclude command. For line by line descriptions of source files, one or more lines of the example can be displayed using the \\line, \\skip, \\skipline, and \\until commands. An internal pointer is used for these commands. The \\dontinclude command sets the pointer to the first line of the example. \par Example: \verbinclude include.cpp Where the example file \c example_test.cpp looks as follows: \verbinclude example_test.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa sections \ref cmdline "\\line", \ref cmdskip "\\skip", \ref cmdskipline "\\skipline", and \ref cmduntil "\\until".
\section cmdinclude \\include \addindex \\include This command can be used to include a source file as a block of code. The command takes the name of an include file as an argument. Source files or directories can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file. If \ itself is not unique for the set of example files specified by the \ref cfg_example_path "EXAMPLE_PATH" tag, you can include part of the absolute path to disambiguate it. Using the \\include command is equivalent to inserting the file into the documentation block and surrounding it with \ref cmdcode "\\code" and \ref cmdendcode "\\endcode" commands. The main purpose of the \\include command is to avoid code duplication in case of example blocks that consist of multiple source and header files. For a line by line description of a source files use the \ref cmddontinclude "\\dontinclude" command in combination with the \ref cmdline "\\line", \ref cmdskip "\\skip", \ref cmdskipline "\\skipline", and \\until commands. \note Doxygen's special commands do not work inside blocks of code. It is allowed to nest C-style comments inside a code block though. \sa section \ref cmdexample "\\example", \ref cmddontinclude "\\dontinclude", and section \ref cmdverbatim "\\verbatim".
\section cmdincludelineno \\includelineno \addindex \\includelineno This command works the same way as \\include, but will add line numbers to the included file. \sa section \ref cmdinclude "\\include".
\section cmdline \\line ( pattern ) \addindex \\line This command searches line by line through the example that was last included using \\include or \\dontinclude until it finds a non-blank line. If that line contains the specified pattern, it is written to the output. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line following the non-blank line that was found (or to the end of the example if no such line could be found). See section \ref cmddontinclude "\\dontinclude" for an example.
\section cmdskip \\skip ( pattern ) \addindex \\skip This command searches line by line through the example that was last included using \\include or \\dontinclude until it finds a line that contains the specified pattern. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line that contains the specified pattern (or to the end of the example if the pattern could not be found). See section \ref cmddontinclude "\\dontinclude" for an example.
\section cmdskipline \\skipline ( pattern ) \addindex \\skipline This command searches line by line through the example that was last included using \\include or \\dontinclude until it finds a line that contains the specified pattern. It then writes the line to the output. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line following the line that is written (or to the end of the example if the pattern could not be found). \par Note: The command: \verbatim\skipline pattern\endverbatim is equivalent to: \verbatim \skip pattern \line pattern\endverbatim See section \ref cmddontinclude "\\dontinclude" for an example.
\section cmduntil \\until ( pattern ) \addindex \\until This command writes all lines of the example that was last included using \\include or \\dontinclude to the output, until it finds a line containing the specified pattern. The line containing the pattern will be written as well. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line following last written line (or to the end of the example if the pattern could not be found). See section \ref cmddontinclude "\\dontinclude" for an example.
\section cmdverbinclude \\verbinclude \addindex \\verbinclude This command includes the file \ verbatim in the documentation. The command is equivalent to pasting the file in the documentation and placing \\verbatim and \\endverbatim commands around it. Files or directories that doxygen should look for can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file.
\section cmdhtmlinclude \\htmlinclude \addindex \\htmlinclude This command includes the file \ as is in the HTML documentation. The command is equivalent to pasting the file in the documentation and placing \\htmlonly and \\endhtmlonly commands around it. Files or directories that doxygen should look for can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file.

\endhtmlonly \section cmda \\a \addindex \\a Displays the argument \ using a special font. Use this command to refer to member arguments in the running text. \par Example: \verbatim ... the \a x and \a y coordinates are used to ... \endverbatim This will result in the following text:

... the \a x and \a y coordinates are used to ...
\section cmdarg \\arg { item-description } \addindex \\arg This command has one argument that continues until the first blank line or until another \\arg is encountered. The command can be used to generate a simple, not nested list of arguments. Each argument should start with a \\arg command. \par Example: Typing: \verbatim \arg \c AlignLeft left alignment. \arg \c AlignCenter center alignment. \arg \c AlignRight right alignment No other types of alignment are supported. \endverbatim will result in the following text:

  • \c AlignLeft left alignment.
  • \c AlignCenter center alignment.
  • \c AlignRight right alignment

No other types of alignment are supported. \par Note: For nested lists, HTML commands should be used. Equivalent to \ref cmdli "\\li"
\section cmdb \\b \addindex \\b Displays the argument \ using a bold font. Equivalent to \word\. To put multiple words in bold use \multiple words\.
\section cmdc \\c \addindex \\c Displays the argument \ using a typewriter font. Use this to refer to a word of code. Equivalent to \word\. \par Example: Typing: \verbatim ... This function returns \c void and not \c int ... \endverbatim will result in the following text:

... This function returns \c void and not \c int ... Equivalent to \ref cmdp "\\p" To have multiple words in typewriter font use \multiple words\.
\section cmdcode \\code \addindex \\code Starts a block of code. A code block is treated differently from ordinary text. It is interpreted as C/C++ code. The names of the classes and members that are documented are automatically replaced by links to the documentation. \sa section \ref cmdendcode "\\endcode", section \ref cmdverbatim "\\verbatim".
\section cmdcopydoc \\copydoc \addindex \\copydoc Copies a documentation block from the object specified by \ and pastes it at the location of the command. This command can be useful to avoid cases where a documentation block would otherwise have to be duplicated or it can be used to extend the documentation of an inherited member. The link object can point to a member (of a class, file or group), a class, a namespace, a group, a page, or a file (checked in that order). Note that if the object pointed to is a member (function, variable, typedef, etc), the compound (class, file, or group) containing it should also be documented for the copying to work. To copy the documentation for a member of a class for instance one can put the following in the documentation \verbatim /*! @copydoc MyClass::myfunction() * More documentation. */ \endverbatim if the member is overloaded, you should specify the argument types explicitly (without spaces!), like in the following: \verbatim /*! @copydoc MyClass::myfunction(type1,type2) */ \endverbatim Qualified names are only needed if the context in which the documentation block is found requires them. The copydoc command can be used recursively, but cycles in the copydoc relation will be broken and flagged as an error. Note that both the brief description and the detailed documentation will be copied. See \ref cmdcopybrief "\\cmdcopybrief" and \ref cmdcopydetails "\\cmdcopydetails" for copying only the brief or detailed part of the comment block.
\section cmdcopybrief \\copybrief Works in a similar way as \ref cmdcopydoc "\\copydoc" but will only copy the brief description, not the detailed documentation.
\section cmdcopydetails \\copydetails Works in a similar way as \ref cmdcopydoc "\\copydoc" but will only copy the detailed documentation, not the brief description.
\section cmddot \\dot \addindex \\dot Starts a text fragment which should contain a valid description of a dot graph. The text fragment ends with \ref cmdenddot "\\enddot". Doxygen will pass the text on to dot and include the resulting image (and image map) into the output. The nodes of a graph can be made clickable by using the URL attribute. By using the command \\ref inside the URL value you can conveniently link to an item inside doxygen. Here is an example: \code /*! class B */ class B {}; /*! class C */ class C {}; /*! \mainpage * * Class relations expressed via an inline dot graph: * \dot * digraph example { * node [shape=record, fontname=Helvetica, fontsize=10]; * b [ label="class B" URL="\ref B"]; * c [ label="class C" URL="\ref C"]; * b -> c [ arrowhead="open", style="dashed" ]; * } * \enddot * Note that the classes in the above graph are clickable * (in the HTML output). */ \endcode
\section cmdmsc \\msc \addindex \\msc Starts a text fragment which should contain a valid description of a message sequence chart. See http://www.mcternan.me.uk/mscgen/ for examples. The text fragment ends with \ref cmdendmsc "\\endmsc". \note The text fragment should only include the part of the message sequence chart that is within the msc {...} block. \note You need to install the mscgen tool, if you want to use this command. Here is an example of the use of the \\msc command. \code /** Sender class. Can be used to send a command to the server. * The receiver will acknowlegde the command by calling Ack(). * \msc * Sender,Receiver; * Sender->Receiver [label="Command()", URL="\ref Receiver::Command()"]; * Sender<-Receiver [label="Ack()", URL="\ref Ack()", ID="1"]; * \endmsc */ class Sender { public: /** Acknowledgement from server */ void Ack(bool ok); }; /** Receiver class. Can be used to receive and execute commands. * After execution of a command, the receiver will send an acknowledgement * \msc * Receiver,Sender; * Receiver<-Sender [label="Command()", URL="\ref Command()"]; * Receiver->Sender [label="Ack()", URL="\ref Sender::Ack()", ID="1"]; * \endmsc */ class Receiver { public: /** Executable a command on the server */ void Command(int commandId); }; \endcode
\section cmddotfile \\dotfile ["caption"] \addindex \\dotfile Inserts an image generated by dot from \ into the documentation. The first argument specifies the file name of the image. doxygen will look for files in the paths (or files) that you specified after the \ref cfg_dotfile_dirs "DOTFILE_DIRS" tag. If the dot file is found it will be used as an input file to the dot tool. The resulting image will be put into the correct output directory. If the dot file name contains spaces you'll have to put quotes ("...") around it. The second argument is optional and can be used to specify the caption that is displayed below the image. This argument has to be specified between quotes even if it does not contain any spaces. The quotes are stripped before the caption is displayed.
\section cmde \\e \addindex \\e Displays the argument \ in italics. Use this command to emphasize words. \par Example: Typing: \verbatim ... this is a \e really good example ... \endverbatim will result in the following text:

... this is a \e really good example ... Equivalent to \ref cmdem "\\em". To emphasis multiple words use \multiple words\.
\section cmdem \\em \addindex \\em Displays the argument \ in italics. Use this command to emphasize words. \par Example: Typing: \verbatim ... this is a \em really good example ... \endverbatim will result in the following text:

... this is a \em really good example ... Equivalent to \ref cmde "\\e"
\section cmdendcode \\endcode \addindex \\endcode Ends a block of code. \sa section \ref cmdcode "\\code"
\section cmdenddot \\enddot \addindex \\enddot Ends a blocks that was started with \ref cmddot "\\dot".
\section cmdendmsc \\endmsc \addindex \\endmsc Ends a blocks that was started with \ref cmdmsc "\\msc".
\section cmdendhtmlonly \\endhtmlonly \addindex \\endhtmlonly Ends a block of text that was started with a \\htmlonly command. \sa section \ref cmdhtmlonly "\\htmlonly".
\section cmdendlatexonly \\endlatexonly \addindex \\endlatexonly Ends a block of text that was started with a \\latexonly command. \sa section \ref cmdlatexonly "\\latexonly".
\section cmdendmanonly \\endmanonly \addindex \\endmanonly Ends a block of text that was started with a \\manonly command. \sa section \ref cmdmanonly "\\manonly".
\section cmdendverbatim \\endverbatim \addindex \\endverbatim Ends a block of text that was started with a \\verbatim command. \sa section \ref cmdendcode "\\endcode", section \ref cmdverbatim "\\verbatim".
\section cmdendxmlonly \\endxmlonly \addindex \\endxmlonly Ends a block of text that was started with a \\xmlonly command. \sa section \ref cmdxmlonly "\\xmlonly".
\section cmdfdollar \\f$ \addindex \\f\$ Marks the start and end of an in-text formula. \sa section \ref formulas "formulas" for an example.
\section cmdfbropen \\f[ \addindex \\f[ Marks the start of a long formula that is displayed centered on a separate line. \sa section \ref cmdfbrclose "\\f]" and section \ref formulas "formulas".
\section cmdfbrclose \\f] \addindex \\f] Marks the end of a long formula that is displayed centered on a separate line. \sa section \ref cmdfbropen "\\f[" and section \ref formulas "formulas".
\section cmdfcurlyopen \\f{environment}{ Marks the start of a formula that is in a specific environment. \note The second \{ is optional and is only to help editors (such as Vim) to do proper syntax highlighting by making the number of opening and closing braces the same.
\section cmdfcurlyclose \\f} Marks the end of a formula that is in a specific environment.
\section cmdhtmlonly \\htmlonly \addindex \\htmlonly Starts a block of text that will be verbatim included in the generated HTML documentation only. The block ends with a endhtmlonly command. This command can be used to include HTML code that is too complex for doxygen (i.e. applets, java-scripts, and HTML tags that require attributes). You can use the \\latexonly and \\endlatexonly pair to provide a proper \f$\mbox{\LaTeX}\f$ alternative. \b Note: environment variables (like \$(HOME) ) are resolved inside a HTML-only block. \sa section \ref cmdmanonly "\\manonly" and section \ref cmdlatexonly "\\latexonly".
\section cmdimage \\image ["caption"] [=] \addindex \\image Inserts an image into the documentation. This command is format specific, so if you want to insert an image for more than one format you'll have to repeat this command for each format. The first argument specifies the output format. Currently, the following values are supported: \c html and \c latex. The second argument specifies the file name of the image. doxygen will look for files in the paths (or files) that you specified after the \ref cfg_image_path "IMAGE_PATH" tag. If the image is found it will be copied to the correct output directory. If the image name contains spaces you'll have to put quotes ("...") around it. You can also specify an absolute URL instead of a file name, but then doxygen does not copy the image nor check its existance. The third argument is optional and can be used to specify the caption that is displayed below the image. This argument has to be specified on a single line and between quotes even if it does not contain any spaces. The quotes are stripped before the caption is displayed. The fourth argument is also optional and can be used to specify the width or height of the image. This is only useful for \f$\mbox{\LaTeX}\f$ output (i.e. format=latex). The \c sizeindication can be either \c width or \c height. The size should be a valid size specifier in \f$\mbox{\LaTeX}\f$ (for example 10cm or 6in or a symbolic width like \\textwidth). Here is example of a comment block: \verbatim /*! Here is a snapshot of my new application: * \image html application.jpg * \image latex application.eps "My application" width=10cm */ \endverbatim And this is an example of how the relevant part of the configuration file may look: \verbatim IMAGE_PATH = my_image_dir \endverbatim \warning The image format for HTML is limited to what your browser supports. For \f$\mbox{\LaTeX}\f$, the image format must be Encapsulated PostScript (eps).

Doxygen does not check if the image is in the correct format. So \e you have to make sure this is the case!
\section cmdlatexonly \\latexonly \addindex \\latexonly Starts a block of text that will be verbatim included in the generated \f$\mbox{\LaTeX}\f$ documentation only. The block ends with a endlatexonly command. This command can be used to include \f$\mbox{\LaTeX}\f$ code that is too complex for doxygen (i.e. images, formulas, special characters). You can use the \\htmlonly and \\endhtmlonly pair to provide a proper HTML alternative. \b Note: environment variables (like \$(HOME) ) are resolved inside a \f$\mbox{\LaTeX}\f$-only block. \sa section \ref cmdlatexonly "\\latexonly" and section \ref cmdhtmlonly "\\htmlonly".
\section cmdmanonly \\manonly \addindex \\manonly Starts a block of text that will be verbatim included in the generated MAN documentation only. The block ends with a endmanonly command. This command can be used to include groff code directly into MAN pages. You can use the \\htmlonly and \\latexonly and \\endhtmlonly and \\endlatexonly pairs to provide proper HTML and \f$\mbox{\LaTeX}\f$ alternatives. \sa section \ref cmdhtmlonly "\\htmlonly" and section \ref cmdlatexonly "\\latexonly".
\section cmdli \\li { item-description } \addindex \\li This command has one argument that continues until the first blank line or until another \\li is encountered. The command can be used to generate a simple, not nested list of arguments. Each argument should start with a \\li command. \par Example: Typing: \verbatim \li \c AlignLeft left alignment. \li \c AlignCenter center alignment. \li \c AlignRight right alignment No other types of alignment are supported. \endverbatim will result in the following text:

  • \c AlignLeft left alignment.
  • \c AlignCenter center alignment.
  • \c AlignRight right alignment

No other types of alignment are supported. \par Note: For nested lists, HTML commands should be used. Equivalent to \ref cmdarg "\\arg"
\section cmdn \\n \addindex \\n Forces a new line. Equivalent to \ and inspired by the printf function.
\section cmdp \\p \addindex \\p Displays the parameter \ using a typewriter font. You can use this command to refer to member function parameters in the running text. \par Example: \verbatim ... the \p x and \p y coordinates are used to ... \endverbatim This will result in the following text:

... the \p x and \p y coordinates are used to ... Equivalent to \ref cmdc "\\c"
\section cmdverbatim \\verbatim \addindex \\verbatim Starts a block of text that will be verbatim included in both the HTML and the \f$\mbox{\LaTeX}\f$ documentation. The block should end with a \\endverbatim block. All commands are disabled in a verbatim block. \warning Make sure you include a \\endverbatim command for each \\verbatim command or the parser will get confused! \sa section \ref cmdcode "\\code", and section \ref cmdverbinclude "\\verbinclude".
\section cmdxmlonly \\xmlonly \addindex \\xmlonly Starts a block of text that will be verbatim included in the generated XML output only. The block ends with a endxmlonly command. This command can be used to include custom XML tags. \sa section \ref cmdhtmlonly "\\htmlonly" and section \ref cmdlatexonly "\\latexonly".
\section cmdbackslash \\\\ \addindex \\\\ This command writes a backslash character (\\) to the HTML and \f$\mbox{\LaTeX}\f$ output. The backslash has to be escaped in some cases because doxygen uses it to detect commands.
\section cmdat \\\@ \addindex \\\@ This command writes an at-sign (\@) to the HTML and \f$\mbox{\LaTeX}\f$ output. The at-sign has to be escaped in some cases because doxygen uses it to detect JavaDoc commands.
\section cmdtilde \\~[LanguageId] \addindex \\~ This command enables/disables a language specific filter. This can be used to put documentation for different language into one comment block and use the \c OUTPUT_LANGUAGE tag to filter out only a specific language. Use \\~language_id to enable output for a specific language only and \\~ to enable output for all languages (this is also the default mode). Example: \verbatim /*! \~english This is english \~dutch Dit is Nederlands \~german Dieses ist deutsch. \~ output for all languages. */ \endverbatim
\section cmdamp \\\& \addindex \\\& This command writes the \& character to output. This character has to be escaped because it has a special meaning in HTML.
\section cmddollar \\\$ \addindex \\\$ This command writes the \$ character to the output. This character has to be escaped in some cases, because it is used to expand environment variables.
\section cmdhash \\\# \addindex \\\# This command writes the \# character to the output. This character has to be escaped in some cases, because it is used to refer to documented entities.
\section cmdlt \\\< \addindex \\\< This command writes the \< character to the output. This character has to be escaped because it has a special meaning in HTML.
\section cmdgt \\\> \addindex \\\> This command writes the \> character to the output. This character has to be escaped because it has a special meaning in HTML.
\section cmdperc \\\% \addindex \\\% This command writes the \% character to the output. This character has to be escaped in some cases, because it is used to prevent auto-linking to word that is also a documented class or struct.
\section cmdquot \\\" \addindex \\\" This command writes the \" character to the output. This character has to be escaped in some cases, because it is used to prevent auto-linking to word that is also a documented class or struct.
