/*! \page autolink Automatic link generation
Most documentation systems have special `see also' sections where links
to other pieces of documentation can be inserted.
Although doxygen also has a command to start such a section (See section
\ref cmdsa "\\sa"), it does allow you to put these kind of links anywhere in the
documentation.
For \f$\mbox{\LaTeX}\f$ documentation a reference to the page number
is written instead of a link. Furthermore, the index at the end of the
document can be used to quickly find the documentation of a member, class,
namespace or file.
For man pages no reference information is generated.
The next sections show how to generate links to the various documented
entities in a source file.
\section linkurl Links to web pages and mail addresses
Doxygen will automatically replace any URLs and mail addresses found in the
documentation by links (in HTML). To manually specify link text, use the
HTML '<tt>a</tt>' tag:
\verbatim <a href="linkURL">link text</a> \endverbatim
which will be automatically translated to other output formats by Doxygen.
\section linkclass Links to classes.
All words in the documentation that correspond to a documented class and
contain at least one non-lower case character will automatically be
replaced by a link to the page containing the
documentation of the class. If you want to prevent that a word
that corresponds to a documented class is replaced by a link you
should put a \% in front of the word.
To link to an all lower case symbol, use \ref cmdref "\\ref".
\section linkfile Links to files.
All words that contain a dot (<tt>.</tt>) that is not the last character
in the word are considered to be file names.
If the word is indeed the name of a documented input file, a link will
automatically be created to the documentation of that file.
\section linkfunc Links to functions.
Links to functions are created if one of the following patterns is
encountered:
<ol>
<li><tt>\<functionName\>"("\<argument-list\>")"</tt>
<li><tt>\<functionName\>"()"</tt>
<li><tt>"::"\<functionName\></tt>
<li><tt>(\<className\>"::")<sup>n</sup>\<functionName\>"("\<argument-list\>")"</tt>
<li><tt>(\<className\>"::")<sup>n</sup>\<functionName\>"("\<argument-list\>")"\<modifiers\></tt>
<li><tt>(\<className\>"::")<sup>n</sup>\<functionName\>"()"</tt>
<li><tt>(\<className\>"::")<sup>n</sup>\<functionName\></tt>
</ol>
where n\>0.
\par Note 1:
Function arguments should be specified with correct types, i.e.
'fun(const std::string&,bool)' or '()' to match any prototype.
\par Note 2:
Member function modifiers (like 'const' and 'volatile')
are required to identify the target, i.e. 'func(int) const' and 'fun(int)'
target different member functions.
\par Note 3:
For JavaDoc compatibility a \# may be used instead of a :: in
the patterns above.
\par Note 4:
In the documentation of a class containing a member foo,
a reference to a global variable is made using "::foo", whereas \#foo
will link to the member.
For non overloaded members the argument list may be omitted.
If a function is overloaded and no matching argument list is specified
(i.e. pattern 2 or 6 is used), a link will be created to the
documentation of one of the overloaded members.
For member functions the class scope (as used in patterns 4 to 7) may
be omitted, if:
<ol>
<li>The pattern points to a documented member that belongs to the same class
as the documentation block that contains the pattern.
<li>The class that corresponds to the documentation blocks that contains
the pattern has a base class that contains a documented member
that matches the pattern.
</ol>
\section linkother Links to variables, typedefs, enum types, enum values and defines.
All of these entities can be linked to in the same way as described in the
previous section. For sake of clarity it is advised to only use
patterns 3 and 7 in this case.
\par Example:
\verbinclude autolink.cpp
\htmlonly
Click <a href="$(DOXYGEN_DOCDIR)/examples/autolink/html/index.html">here</a>
for the corresponding HTML documentation that is generated by Doxygen.
\endhtmlonly
\section resolving typedefs.
Typedefs that involve classes, structs and unions, like
\verbatim
typedef struct StructName TypeName
\endverbatim
create an alias for StructName, so links will be generated to StructName,
when either StructName itself or TypeName is encountered.
\par Example:
\verbinclude restypedef.cpp
\htmlonly
Click <a href="$(DOXYGEN_DOCDIR)/examples/restypedef/html/restypedef_8cpp.html">here</a>
for the corresponding HTML documentation that is generated by Doxygen.
\endhtmlonly
