I have read the documentation and hve seen that there is an add_vertex method that allows a vertex to be added at the same time that a vertex property is set. Unfortunately the docs do not make it clear to me exactly what type I'm supposed to pass as the vertex property. If I have code like the following where I get a vertex property map from a graph, add the vertex, and then set the property: member_names_t member_names = boost::get(boost::vertex_name_t(), __graph); member_vertex_t vertex = boost::add_vertex(__graph); boost::put(member_names, vertex, name); How can I edit this code to using the add_vertex call from the MutablePropertyGraph ala: // how to express vp? member_vertex_t vertex = boost::add_vertex(vp, __graph); --aj
