boost::typed_identity_property_map<T> typedef boost::typed_identity_propoperty_map<std::size_t> boost::identity_property_map
The typed_identity_property_map property map applies the identity function, that is, it just returns a copy of the key object that was input. The key and value types are both the same as the template parameter T. The identity_property_map name is for the common case where the key and value type are std::size_t (this name is deprecated for use within Boost.Graph).
Note: Previously the function get() and operator[] for identity_property_map were overloaded to return a copy of keys of any type, i.e., not just size_t. These overloads are now deprecated, because they did not adhere to the property map concepts.
