61<h1>Graph Legend</h1>This page explains how to interpret the graphs that are generated by doxygen.<p>
62Consider the following example: <div class="fragment"><pre class="fragment"><span class="comment">/*! Invisible class because of truncation */</span>
63<span class="keyword">class </span>Invisible { };
64<span class="comment"></span>
65<span class="comment">/*! Truncated class, inheritance relation is hidden */</span>
66<span class="keyword">class </span>Truncated : <span class="keyword">public</span> Invisible { };
67
68<span class="comment">/* Class not documented with doxygen comments */</span>
69<span class="keyword">class </span>Undocumented { };
70<span class="comment"></span>
71<span class="comment">/*! Class that is inherited using public inheritance */</span>
72<span class="keyword">class </span>PublicBase : <span class="keyword">public</span> Truncated { };
73<span class="comment"></span>
74<span class="comment">/*! A template class */</span>
75<span class="keyword">template</span>&lt;<span class="keyword">class</span> T&gt; <span class="keyword">class </span>Templ { };
76<span class="comment"></span>
77<span class="comment">/*! Class that is inherited using protected inheritance */</span>
78<span class="keyword">class </span>ProtectedBase { };
79<span class="comment"></span>
80<span class="comment">/*! Class that is inherited using private inheritance */</span>
81<span class="keyword">class </span>PrivateBase { };
82<span class="comment"></span>
83<span class="comment">/*! Class that is used by the Inherited class */</span>
84<span class="keyword">class </span>Used { };
85<span class="comment"></span>
86<span class="comment">/*! Super class that inherits a number of other classes */</span>
87<span class="keyword">class </span>Inherited : <span class="keyword">public</span> PublicBase,
88                  <span class="keyword">protected</span> ProtectedBase,
89                  <span class="keyword">private</span> PrivateBase,
90                  <span class="keyword">public</span> Undocumented,
91                  <span class="keyword">public</span> Templ&lt;int&gt;
92{
93  <span class="keyword">private</span>:
94    Used *m_usedClass;
95};
96</pre></div> This will result in the following graph:<p>
97<center><div align="center">
98<img src="graph_legend.png" alt="graph_legend.png">
99</div>
100</center> <p>
101The boxes in the above graph have the following meaning: <ul>
102<li>
103A filled gray box represents the struct or class for which the graph is generated. </li>
104<li>
105A box with a black border denotes a documented struct or class. </li>
106<li>
107A box with a grey border denotes an undocumented struct or class. </li>
108<li>
109A 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. </li>
110</ul>
111The arrows have the following meaning: <ul>
112<li>
113A dark blue arrow is used to visualize a public inheritance relation between two classes. </li>
114<li>
115A dark green arrow is used for protected inheritance. </li>
116<li>
117A dark red arrow is used for private inheritance. </li>
118<li>
119A 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>
120<li>
121A 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. </li>
122</ul>
