clang: Graph Legend (original) (raw)

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

Consider the following example:

class Invisible { };

class Truncated : public Invisible { };

class Undocumented { };

class PublicBase : public Truncated { };

template class Templ { };

class ProtectedBase { };

class PrivateBase { };

class Inherited : public PublicBase,

protected ProtectedBase,

private PrivateBase,

public Undocumented,

public Templ

{

private:

Used *m_usedClass;

};

This will result in the following graph:

The boxes in the above graph have the following meaning:

• A filled gray 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 gray 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 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 labelled 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 labelled with the template parameters of the instance.
