Graph Legend

This page explains how to interpret the graphs that are generated by doxygen.

+Consider the following example: 

/*! Invisible class because of truncation */
+class Invisible { };
+
+/*! Truncated class, inheritance relation is hidden */
+class Truncated : public Invisible { };
+
+/* Class not documented with doxygen comments */
+class Undocumented { };
+
+/*! Class that is inherited using public inheritance */
+class PublicBase : public Truncated { };
+
+/*! A template class */
+template<class T> class Templ { };
+
+/*! Class that is inherited using protected inheritance */
+class ProtectedBase { };
+
+/*! Class that is inherited using private inheritance */
+class PrivateBase { };
+
+/*! Class that is used by the Inherited class */
+class Used { };
+
+/*! Super class that inherits a number of other classes */
+class Inherited : public PublicBase,
+                  protected ProtectedBase,
+                  private PrivateBase,
+                  public Undocumented
+                  public Templ<int>
+{
+  private:
+    Used *m_usedClass;
+};
+
If the MAX_DOT_GRAPH_HEIGHT tag in the configuration file is set to 240 this will result in the following graph:

+

+graph_legend.png +
+

+The boxes in the above graph have the following meaning:

    +
  • +A filled black box represents the struct or class for which the graph is generated.
    • +
  • +A box with a black border denotes a documented struct or class.
    • +
  • +A box with a grey border denotes an undocumented struct or class.
    • +
  • +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.
    • +
+The arrows have the following meaning:
    +
  • +A dark blue arrow is used to visualize a public inheritance relation between two classes.
    • +
  • +A dark green arrow is used for protected inheritance.
    • +
  • +A dark red arrow is used for private inheritance.
    • +
  • +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.
    • +
  • +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.
