Re: [BGL] Property map question

Sorry - my previous post got cut in half somewhere in transit. This is a reposting: What determines when boost::get(Graph, vertex_myproperty_t) returns a boost::property_map::type vs. a ::const_type? Suppose: enum vertex_myproperty_t { vertex_myproperty = 12345}; BOOST_INSTALL_PROPERTY(vertex,myproperty); typedef property vertex_properties_t; typedef adjacency_list graph_t; typedef property_map::type vertex_myproperty_map_t; graph_t Graph;
