Property Map
property_map<PropertyGraph, PropertyTag>
This is the traits class that produces the type for a property map object for a particular graph type. The property is specified by the PropertyTag template parameter. Graph classes must specialize this traits class to provide their own implementation for property maps.
template <class Graph, class PropertyTag>
struct property_map {
typedef ... type;
typedef ... const_type;
};
boost/graph/properties.hpp
| Map Type | type | The (mutable) property map type for mapping vertex or edge descriptors of the graph to their associated property values, where the property is specified by PropertyTag. This type is a property map. |
| Const Map Type | const_type | The (non-mutable) property map type for mapping vertex or edge descriptors of the graph to their associated property values, where the property is specified by PropertyTag. This type is a property map. |
