<hr><h1>Graph Legend</h1>This page explains how to interpret the graphs that are generated by doxygen.
<p>
Consider the following example: <div class="fragment"><pre><span class="comment">/*! Invisible class because of truncation */</span>
<span class="keyword">class </span>Invisible { };
<span class="comment"></span>
<span class="comment">/*! Truncated class, inheritance relation is hidden */</span>
<span class="keyword">class </span>Truncated : <span class="keyword">public</span> Invisible { };
<span class="comment">/* Class not documented with doxygen comments */</span>
<span class="keyword">class </span>Undocumented { };
<span class="comment"></span>
<span class="comment">/*! Class that is inherited using public inheritance */</span>
<span class="keyword">class </span>PublicBase : <span class="keyword">public</span> Truncated { };
<span class="comment"></span>
<span class="comment">/*! A template class */</span>
<span class="keyword">template</span><<span class="keyword">class</span> T> <span class="keyword">class </span>Templ { };
<span class="comment"></span>
<span class="comment">/*! Class that is inherited using protected inheritance */</span>
<span class="keyword">class </span>ProtectedBase { };
<span class="comment"></span>
<span class="comment">/*! Class that is inherited using private inheritance */</span>
<span class="keyword">class </span>PrivateBase { };
<span class="comment"></span>
<span class="comment">/*! Class that is used by the Inherited class */</span>
<span class="keyword">class </span>Used { };
<span class="comment"></span>
<span class="comment">/*! Super class that inherits a number of other classes */</span>
<span class="keyword">class </span>Inherited : <span class="keyword">public</span> PublicBase,
<span class="keyword">protected</span> ProtectedBase,
<span class="keyword">private</span> PrivateBase,
<span class="keyword">public</span> Undocumented
<span class="keyword">public</span> Templ<int>
{
<span class="keyword">private</span>:
Used *m_usedClass;
};
</pre></div> If the <code>MAX_DOT_GRAPH_HEIGHT</code> tag in the configuration file is set to 240 this will result in the following graph:
<p>
<center>
<img alt="" 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 forwhich 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. <li>A yellow dashed arrow denotes a relation between a template instance and the template class it was instantiated from. The arrow is labeled with the template parameters of the instance. </ul>
