Invisible class because of truncation */</font> <font class="keyword">class </font>Invisible { }; <font class="comment"></font> <font class="comment">/*! Truncated class, inheritance relation is hidden */</font> <font class="keyword">class </font>Truncated : <font class="keyword">public</font> Invisible { }; <font class="comment">/* Class not documented with doxygen comments */</font> <font class="keyword">class </font>Undocumented { }; <font class="comment"></font> <font class="comment">/*! Class that is inherited using public inheritance */</font> <font class="keyword">class </font>PublicBase : <font class="keyword">public</font> Truncated { }; <font class="comment"></font> <font class="comment">/*! Class that is inherited using protected inheritance */</font> <font class="keyword">class </font>ProtectedBase { }; <font class="comment"></font> <font class="comment">/*! Class that is inherited using private inheritance */</font> <font class="keyword">class </font>PrivateBase { }; <font class="comment"></font> <font class="comment">/*! Class that is used by the Inherited class */</font> <font class="keyword">class </font>Used { }; <font class="comment"></font> <font class="comment">/*! Super class that inherits a number of other classes */</font> <font class="keyword">class </font>Inherited : <font class="keyword">public</font> PublicBase, <font class="keyword">protected</font> ProtectedBase, <font class="keyword">private</font> PrivateBase, <font class="keyword">public</font> Undocumented { <font class="keyword">private</font>: Used *m_usedClass; };</pre></div> If the <code>MAX_DOT_GRAPH_HEIGHT</code> tag in the configuration file is set to 200 this will result in the following graph: <p> <center> <img src="graph_legend.gif"></center> <p> The boxes in the above graph have the following meaning: <ul> <li>A filled black box represents the struct or class for which the graph is generated. <li>A box with a black border denotes a documented struct or class. <li>A box with a grey border denotes an undocumented struct or class. <li>A box with a red border denotes a documented struct or class for which not all inheritance/containment relations are shown. A graph is truncated if it does not fit within the specified boundaries.</ul> The arrows have the following meaning: <ul> <li>A dark blue arrow is used to visualize a public inheritance relation between two classes. <li>A dark green arrow is used for protected inheritance. <li>A dark red arrow is used for private inheritance. <li>A purple dashed arrow is used if a class is contained or used by another class. The arrow is labeled with the variable(s) through which the pointed class or struct is accessible. </ul> <hr> <table cellspacing=10 cellpadding=0 border=0 width=100%> <tr valign=middle><td><font size=-1>Documentation automatically generated by <a href="http://www.stack.nl/~dimitri/doxygen/"><img border=0 align=center src="doxygen.gif" alt="doxygen"></a> written by <a href="mailto:dimitri@stack.nl">Dimitri van Heesch</a>.</font></td> <td align=right><font size=-1>Project hosted at <br><a href="http://sourceforge.net"><img align=middle src="http://sourceforge.net/sflogo.php?group_id=25445&type=1" width="88" height="31" border="0" alt="Hosted by SourceForge"></a></font></td></tr></table>
