property_map<[PropertyGraph](./PropertyGraph.html),[PropertyTag](./PropertyTag.html)>

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;
  };

Associated Types

| Map Type | type | The (mutable) property map type for mapping vertex or edge desriptors 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 desriptors of the graph to their associated property values, where the property is specified by PropertyTag. This type is a property map. |
