Detailed Description

template<typename VertexProperty>
struct boost::graph::internal_vertex_name< VertexProperty >

Trait used to extract the internal vertex name from a vertex property.

To enable the use of internal vertex names in a graph type, specialize the internal_vertex_name trait for your graph property (e.g., a City class, which stores information about the vertices in a road map).

Member Typedef Documentation

template<typename VertexProperty>

typedef void boost::graph::internal_vertex_name< VertexProperty >::type

The type field provides a function object that extracts a key from the VertexProperty.

The function object type must have a nested result_type that provides the type of the key. For more information, see the KeyExtractor concept in the Boost.MultiIndex documentation: type must either be void (if VertexProperty does not have an internal vertex name) or a model of KeyExtractor.
