Graph Legend

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 { };

/*! 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
{
  private:
    Used *m_usedClass;
};

MAX_DOT_GRAPH_HEIGHT

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 for which not all inheritance/containment relations are shown. A graph is truncated if it does not fit within the specified boundaries.

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.
