/*! \page commands Special Commands
\section cmd_intro Introduction
All commands in the documentation start with a backslash (\\) or an
at-sign (\@). 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 \ braces are used the argument is a single word.
If (round) braces are used the argument extends until the end of the line
on which the command was found.
If {curly} braces are used the argument extends until the next paragraph.
Paragraphs are delimited by a blank line or by a section indicator. Note that
{curly} braces are also used for command options, here the braces are mandatory
and just 'normal' characters. The starting curly brace has to directly follow
the command, so without whitespace.
\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 \c \@{ and \c \@} like this:
\verbatim
/*! \addtogroup mygrp
* Additional documentation for group 'mygrp'
* @{
*/
/*!
* A function
*/
void func1()
{
}
/*! Another function */
void func2()
{
}
/*! @} */

\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 \c 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 be
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 cmdhidecallgraph \\hidecallgraph
\addindex \\hidecallgraph
When this command is put in a comment block of a function or method
and then doxygen will not generate a call graph for that function. The
call graph will not be 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.

\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 \c YES, then doxygen will
generate a caller graph for that function (provided the implementation of the
function or method is called by other documented functions). The caller graph will be
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 cmdshowrefby \\showrefby
\addindex \\showrefby
When this command is put in a comment block of a function, method or variable,
then doxygen will generate an overview for that function, method, variable of
the, documented, functions and methods that call / use it.
The overview will be generated regardless of the value of
\ref cfg_referenced_by_relation "REFERENCED_BY_RELATION".
\note The completeness (and correctness) of the overview depends on the
doxygen code parser which is not perfect.

\addindex \\hiderefby
When this command is put in a comment block of a function, method or variable
then doxygen will not generate an overview for that function, method or
variable of the functions and methods that call / use it.
The overview will not be generated regardless of the value of
\ref cfg_referenced_by_relation "REFERENCED_BY_RELATION".
\note The completeness (and correctness) of the overview depends on the
doxygen code parser which is not perfect.

When this command is put in a comment block of a function or method,
then doxygen will generate an overview for that function or method of the
functions and methods that call it.
The overview will be generated regardless of the value of
\ref cfg_references_relation "REFERENCES_RELATION".

When this command is put in a comment block of a function or method
and then doxygen will not generate an overview for that function or method of
the functions and methods that call it.
The overview will not be generated regardless of the value of
\ref cfg_references_relation "REFERENCES_RELATION".

\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 \ref cmdclass "\\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 be specified using
the \ref cmdheaderfile "\\headerfile" command.
\par Example:
\include class.h
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{class_example}{Class example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\section cmddef \\def
\addindex \\def
Indicates that a comment block contains documentation for a
\c \#define macro.
\par Example:
\include define.h
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{define_8h}{Define example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\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", and
\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 with respect to the other directories
in the project.
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 \c \\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:
\include enum.h
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{class_enum___test}{Enum example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\section cmdexample \\example['{lineno}']
\addindex \\example
Indicates that a comment block contains documentation for a source code
example. The name of the source file is \.
The contents of this file will be included in the documentation, just after the
documentation contained in the comment block.
You can add option `{lineno}` to enable line numbers for the example if desired.
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 than one source file is needed for the example,
the \ref cmdinclude "\\include" command can be used.
\par Example:
\include example.cpp
Where the example file \c example_test.cpp looks as follows:
\include example_test.cpp
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{example_test_8cpp-example}{Example example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\sa section \ref cmdinclude "\\include".
\section cmdendinternal \\endinternal
\addindex \\endinternal
This command ends a documentation fragment that was started with a
\ref cmdinternal "\\internal" command. The text between \ref cmdinternal "\\internal" and
\c \\endinternal will only be visible
if \ref cfg_internal_docs "INTERNAL_DOCS" is set to \c YES.
\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
\latexonly
See \hyperlink{extends_example}{Extends example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\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 \c \\file is left blank) then the documentation block that
contains the \c \\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:
\include file.h
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{file_example}{File example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\note In the above example \ref cfg_javadoc_autobrief "JAVADOC_AUTOBRIEF"
has been set to \c 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
\c \\fn command on a \e single line, since the argument ends at the end
of the line!
This command is equivalent to \ref cmdvar "\\var", \ref cmdtypedef "\\typedef",
and \ref cmdproperty "\\property".
\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:
\include func.h
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{class_fn___test}{Fn example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\sa sections \ref cmdvar "\\var", \ref cmdproperty "\\property", 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 "\\class".
The \ name refers to the file that should be 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 double quotes or sharp brackets around the name.
By default sharp brackets are used if just the name is given.
If a pair of double quotes is given for either the \ or
\ argument, the current file (in which the command was found)
will be used but with quotes. So for a comment block with a \c \\headerfile
command inside a file test.h, the following three commands are equivalent:
\verbatim
\headerfile test.h "test.h"
\headerfile test.h ""
\headerfile "" \endverbatim
To get sharp brackets you do not need to specify anything,
but if you want to be explicit you could use any of the following:
\verbatim
\headerfile test.h
\headerfile test.h <>
\headerfile <> \endverbatim
To globally reverse the default include representation to
local includes you can set
\ref cfg_force_local_includes "FORCE_LOCAL_INCLUDES" to \c YES.
To disable the include information altogether set
\ref cfg_show_include_files "SHOW_INCLUDE_FILES" to \c NO.
\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. The maximum number of initialization lines
can be changed by means of the configuration parameter
\ref cfg_max_initializer_lines "MAX_INITIALIZER_LINES", the default
value is 30.
\sa section \ref cmdshowinitializer "\\showinitializer".
\section cmdidlexcept \\idlexcept
\addindex \\idlexcept
Indicates that a comment block contains documentation for a
IDL exception with name \.
\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
\latexonly
See \hyperlink{extends_example}{Implements example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\sa section \ref cmdextends "\\extends" and section
\ref cmdmemberof "\\memberof"
\section cmdingroup \\ingroup ( [])
\addindex \\ingroup
If the \c \\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 arguments of the
\ref cmdclass "\\class" command.
\sa section \ref cmdclass "\\class".
\section cmdinternal \\internal
\addindex \\internal
This command starts a documentation fragment that is meant for internal
use only. The fragment naturally ends at the end of the comment block.
You can also force the internal section to end earlier by using the
\ref cmdendinternal "\\endinternal" command.
If the \c \\internal command is put inside a section
(see for example \ref cmdsection "\\section") all subsections after the
command are considered to be internal as well. Only a new section at the
same level will end the fragment that is considered internal.
You can use \ref cfg_internal_docs "INTERNAL_DOCS" in the configuration file
to show (\c YES) or hide (\c NO) the internal documentation.
\sa section \ref cmdendinternal "\\endinternal".
\section cmdmainpage \\mainpage [(title)]
\addindex \\mainpage
If the \c \\mainpage command is placed in a comment block the
block is used to customize the index page (in HTML) or
the first chapter (in \LaTeX).
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 \c \\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 cmdref "\\ref" index.
\sa section \ref cmdsection "\\section",
section \ref cmdsubsection "\\subsection", and
section \ref cmdpage "\\page".
\section cmdmemberof \\memberof
\addindex \\memberof
This command makes 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.
\sa sections \ref cmdpublicsection "\\publicsection",
\ref cmdprotectedsection "\\protectedsection" and
\ref cmdprivatesection "\\privatesection".
\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 \c NO in this case.
\par Note 2:
The \c \\overload command does not work inside a one-line comment.
\par Example:
\include overload.cpp
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{class_overload___test}{Overload example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\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
\LaTeX generator
starts a new section in the chapter 'Page documentation'.
\par Example:
\include page.doc
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{page_example}{Page example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\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 \ref cfg_case_sense_names "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
Indicates that the member documented by 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 \ref cmdprivatesection "\\privatesection".
\sa sections \ref cmdmemberof "\\memberof", \ref cmdpublic "\\public",
\ref cmdprotected "\\protected" and \ref cmdprivatesection "\\privatesection".
\section cmdprivatesection \\privatesection
\addindex \\privatesection
Starting a section of private members, in a way similar to the
"private:" class marker in C++.
Indicates that the member documented by the comment block is private,
i.e., should only be accessed by other members in the same class.
\sa sections \ref cmdmemberof "\\memberof", \ref cmdpublic "\\public",
\ref cmdprotected "\\protected" and \ref cmdprivate "\\private".
\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 \ref cmdfn "\\fn",
\ref cmdtypedef "\\typedef", and \ref cmdvar "\\var".
\sa sections \ref cmdfn "\\fn", \ref cmdtypedef "\\typedef", and
\ref cmdvar "\\var".
\section cmdprotected \\protected
\addindex \\protected
Indicates that the member documented by 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 \ref cmdprotectedsection "\\protectedsection".
\sa sections \ref cmdmemberof "\\memberof", \ref cmdpublic "\\public",
\ref cmdprivate "\\private" and \ref cmdprotectedsection "\\protectedsection".
\section cmdprotectedsection \\protectedsection
\addindex \\protectedsection
Starting a section of protected members, in a way similar to the
"protected:" class marker in C++.
Indicates that the member documented by the comment block is protected,
i.e., should only be accessed by other members in the same or derived
classes.
\sa sections \ref cmdmemberof "\\memberof", \ref cmdpublic "\\public",
\ref cmdprivate "\\private" and \ref cmdprotected "\\protected".
\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 \ref cmdclass "\\class" command.
\sa section \ref cmdclass "\\class".
\section cmdpublic \\public
\addindex \\public
Indicates that the member documented by 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 \ref cmdpublicsection "\\publicsection".
\sa sections \ref cmdmemberof "\\memberof", \ref cmdprotected "\\protected",
\ref cmdprivate "\\private" and \ref cmdpublicsection "\\publicsection".
\section cmdpublicsection \\publicsection
\addindex \\publicsection
Starting a section of public members, in a way similar to the
"public:" class marker in C++.
Indicates that the member documented by the comment block is public,
i.e., can be accessed by any other class or function.
\sa sections \ref cmdmemberof "\\memberof", \ref cmdprotected "\\protected",
\ref cmdprivate "\\private" and \ref cmdpublic "\\public".
\section cmdpure \\pure
\addindex \\pure
Indicates that the member documented by the comment block is pure virtual,
i.e., it is abstract and has no implementation associated with it.
This command is intended for use only when
the language does not support the concept of pure virtual methods natively
(e.g. C, PHP 4).
\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:
\include relates.cpp
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{class_string}{Relates example}

\addindex \\related
Equivalent to \ref cmdrelates "\\relates"
\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 it at 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 cmdrelatedalso \\relatedalso
\addindex \\relatedalso
Equivalent to \ref cmdrelatesalso "\\relatesalso"
\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.
The maximum number of initialization lines
can be changed by means of the configuration parameter
\ref cfg_max_initializer_lines "MAX_INITIALIZER_LINES", the default value is
30.
\sa section \ref cmdhideinitializer "\\hideinitializer".
\section cmdstatic \\static
\addindex \\static
Indicates that the member documented by the comment block is static,
i.e., it works on a class, instead of on an instance of the class.
This command is intended for use only when
the language does not support the concept of static methods natively (e.g. C).
\section cmdstruct \\struct [] []
\addindex \\struct
Indicates that a comment block contains documentation for a
struct with name \. The arguments are equal to the arguments of the
\ref cmdclass "\\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 \ref cmdfn "\\fn",
\ref cmdproperty "\\property", and \ref cmdvar "\\var".
\sa section \ref cmdfn "\\fn", \ref cmdproperty "\\property", 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 arguments of the
\ref cmdclass "\\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 \ref cmdfn "\\fn",
\ref cmdproperty "\\property", and \ref cmdtypedef "\\typedef".
Note that for PHP one can also specify the type of the variable.
The syntax is similar as for the `phpDocumentor` but the description has to start
at the next line, i.e.
\verbatim
@var datatype $varname
Description
\endverbatim
\sa section \ref cmdfn "\\fn", \ref cmdproperty "\\property", and \ref cmdtypedef "\\typedef".
\section cmdvhdlflow \\vhdlflow [(title for the flow chart)]
\addindex \\vhdlflow
This is a VHDL specific command, which can be put in the documentation of a process to
produce a flow chart of the logic in the process.
Optionally a title for the flow chart can be given.
\note Currently the flow chart will only appear in the HTML output.
\section cmdweakgroup \\weakgroup [(title)]
\addindex \\weakgroup
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 section \ref cmdaddtogroup "\\addtogroup".
\htmlonly
\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 \c \\attention commands will be joined into a single paragraph.
The \c \\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 \c \\author commands will be joined into a single paragraph.
Each author description will start a new line. Alternatively, one \c \\author command
may mention several authors. The \c \\author command ends when a blank line or some other
sectioning command is encountered.
\par Example:
\include author.cpp
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{class_some_nice_class}{Author example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\section cmdauthors \\authors { list of authors }
\addindex \\authors
Equivalent to \ref cmdauthor "\\author".
\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
\c \\brief commands are present they will be joined. See section
\ref cmdauthor "\\author" for an example.
Synonymous to \ref cmdshort "\\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 \c \\bug commands will be joined into a single paragraph.
Each bug description will start on a new line.
Alternatively, one \c \\bug command may mention
several bugs. The \c \\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 [(section-label)]
\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 \c \\cond and \ref cmdendcond "\\endcond" 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. The section label can be a
logical expression build of section labels, round brackets, && (AND), || (OR) and ! (NOT).
If you use an expression you need to wrap it in round brackets, i.e
\\cond (!LABEL1 && LABEL2).
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 \ref cfg_enabled_sections "ENABLED_SECTIONS"
contains \c TEST, or \c DEV
\sa sections \ref cmdendcond "\\endcond" and \ref cfg_enabled_sections "ENABLED_SECTIONS".
\note Due to the moment of parsing the \c \\cond and \ref cmdendcond "\\endcond" commands cannot
be used in \ref cfg_aliases "ALIASES".
\section cmdcopyright \\copyright { copyright description }
\addindex \\copyright
Starts a paragraph where the copyright of an entity can be described.
This paragraph will be indented.
The text of the paragraph has no special internal structure.
See section \ref cmdauthor "\\author" for an example.
\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 \c \\date commands will be joined into a single paragraph.
Each date description will start on a new line.
Alternatively, one \c \\date command may mention
several dates. The \c \\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 description }
\addindex \\details
Just like \ref cmdbrief "\\brief" starts a brief description, \c \\details
starts the detailed description. You can also start a new paragraph (blank line)
then the \c \\details command is not needed.
\section cmdnoop \\noop ( text to be ignored )
\addindex \\noop
All the text, including the command, till the end of the line is ignored.
The command will most commonly be used in combination with \ref cfg_aliases "ALIASES"
to ignore not supported commands that are present for e.g. other processing tools.
\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 \ref cmdif "\\if", \ref cmdifnot "\\ifnot", or \ref cmdelseif "\\elseif"
command.
\sa \ref cmdif "\\if", \ref cmdifnot "\\ifnot", \ref cmdelseif "\\elseif",
\ref cmdendif "\\endif."
\section cmdelseif \\elseif (section-label)
\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. The section label can be a logical expression
build of section names, round brackets, && (AND), || (OR) and ! (NOT).
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 section \ref cmdcond "\\cond".
\note Due to the moment of parsing the \c \\endcond and \ref cmdcond "\\cond" commands cannot
be used in \ref cfg_aliases "ALIASES".
\section cmdendif \\endif
\addindex \\endif
Ends a conditional section that was started by \ref cmdif "\\if" or \ref cmdifnot "\\ifnot"
For each \ref cmdif "\\if" or \ref cmdifnot "\\ifnot" one and only one matching
\ref cmdendif "\\endif" must follow.
\sa sections \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 \c \\exception commands will be joined into a single paragraph.
Each exception description will start on a new line.
The \c \\exception description ends when a blank line or some other
sectioning command is encountered. See section \ref cmdfn "\\fn" for an
example.
\section cmdif \\if (section-label)
\addindex \\if
Starts a conditional documentation section. The section ends
with a matching \ref cmdendif "\\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.
The section label can be a logical expression
build of section names, round brackets, && (AND), || (OR) and ! (NOT).
If you use an expression you need to wrap it in round brackets, i.e
\\cond (!LABEL1 && LABEL2).
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 \ref cfg_enabled_sections "ENABLED_SECTIONS" can be used to enable either \c english or \c dutch.
\sa sections \ref cmdendif "\\endif", \ref cmdifnot "\\ifnot",
\ref cmdelse "\\else", \ref cmdelseif "\\elseif", and
\ref cfg_enabled_sections "ENABLED_SECTIONS".
\section cmdifnot \\ifnot (section-label)
\addindex \\ifnot
Starts a conditional documentation section. The section ends
with a matching \ref cmdendif "\\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. The section label can be a logical expression
build of section names, round brackets, && (AND), || (OR) and ! (NOT).
\sa sections \ref cmdendif "\\endif", \ref cmdif "\\if",
\ref cmdelse "\\else", and \ref cmdelseif "\\elseif", and
\ref cfg_enabled_sections "ENABLED_SECTIONS".
\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 \c \\invariant commands will be joined into a single paragraph.
Each invariant description will start on a new line.
Alternatively, one \c \\invariant command may mention
several invariants. The \c \\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 \c \\note commands will be joined into a single paragraph.
Each note description will start on a new line.
Alternatively, one \c \\note command may mention
several notes. The \c \\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 \ref cmdparam "\\param" or \ref cmdwarning "\\warning") without ending that command.
The text of the paragraph has no special internal structure. All visual
enhancement commands may be used inside the paragraph.
The \c \\par command ends when a blank line or some other
sectioning command is encountered.
\par Example:
\include par.cpp
\htmlonly
Click here
for the corresponding HTML documentation that is generated by doxygen.
\endhtmlonly
\latexonly
See \hyperlink{class_par___test}{Par example}
for the corresponding \mbox{\LaTeX} documentation that is generated by doxygen.
\endlatexonly
\section cmdparam \\param '['dir']' { 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 \c \\param command has an optional attribute, `dir`, specifying the direction
of the parameter. Possible values are "[in]", "[in,out]", and "[out]",
note the [square] brackets in this description.
When a parameter is both input and output, [in,out] is used as attribute.
Here is an example for the function \c 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
The parameter description is a paragraph with no special internal structure.
All visual enhancement commands may be used inside the paragraph.
Multiple adjacent \c \\param commands will be joined into a single paragraph.
Each parameter description will start on a new line.
The \c \\param description ends when a blank line or some other
sectioning command is encountered. See section \ref cmdfn "\\fn" for an
example.
Note that you can also document multiple parameters with a single
\c \\param command using a comma separated list. Here is an example:
\code
/** Sets the position.
* @param x,y,z Coordinates of the position in 3D space.
*/
void setPosition(double x,double y,double z,double t)
{
}
\endcode
Note that for PHP one can also specify the type (or types if you
separate them with a pipe symbol) which are allowed for a parameter
(as this is not part of the definition).
The syntax is the same as for the `phpDocumentor`, i.e.
\verbatim
@param datatype1|datatype2 $paramname description
\endverbatim
\section cmdparblock \\parblock
\addindex \\parblock
For commands that expect a single paragraph as argument
(such as \ref cmdpar "\\par", \ref cmdparam "\\param" and \ref cmdwarning "\\warning"),
the \ref cmdparblock "\\parblock" command allows to start a
description that covers multiple paragraphs, which then ends with
\ref cmdendparblock "\\endparblock".
Example:
\verbatim
/** Example of a param command with a description consisting of two paragraphs
* \param p
* \parblock
* First paragraph of the param description.
*
* Second paragraph of the param description.
* \endparblock
* Rest of the comment block continues.
*/
\endverbatim
Note that the \c \\parblock command may also appear directly after
\ref cmdparam "\\param"'s first argument.
\section cmdendparblock \\endparblock
\addindex \\endparblock
This ends a block of paragraphs started with \ref cmdparblock "\\parblock".
\section cmdtparam \\tparam { description }
\addindex \\tparam

\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 an
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 fourth 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 \c "todo", \c "test", \c "bug" and \c "deprecated" are predefined.
To get an idea on how to use the \c \\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 \c \\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
\c \\xrefitem command.
In case parameter "(heading)" is the empty string no heading is generated. This can be useful
when used in combination with the \ref cmdpage "\\page" command e.g.
\verbatim
/** @page my_errors My Errors
* @brief Errors page
*
* Errors page contents.
*/
/** \error ERROR 101: in case a file can not be opened.
Check about file system read/write access. */
#define MY_ERR_CANNOT_OPEN_FILE 101
/** \error ERROR 102: in case a file can not be closed.
Check about file system read/write access. */
#define MY_ERR_CANNOT_CLOSE_FILE 102
\endverbatim
with \c \\error defined as
\verbatim ALIASES += "error=\xrefitem my_errors \"\" \"\"" \endverbatim
