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. </li>
</ul>
<p>The arrows have the following meaning: </p>
<ul>
<li>
A dark blue arrow is used to visualize a public inheritance relation between two classes. </li>
<li>
A dark green arrow is used for protected inheritance. </li>
<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. </li>
