All,
I have:
typedef boost::adjacency_list<boost::listS, boost::listS, boost::undirectedS, place, link> mapType;
place* newPlace = new place("here-and-there"); mapType::vertex_descriptor newPlaceDesc = add_vertex(*newPlace, theMap);
where the destructor of place is:
place::~place() { // Just to make sure... std::cout << "Deleting place " << name << std::endl; // ... }
When I run that, I do get:
Deleting place here-and-there
just after adding the vertex. In other words, a property is being deleted, probably a copy of the one I gave. I even tried (to make it explicitly like the documentation says):
mapType::vertex_descriptor newPlaceDesc = add_vertex(static_cast<const place&>(*newPlace), theMap);
and the same happens.
Is that suppose to happen?
Cheers,
Fred Hola Fred, I'm pretty sure that add_vertex() takes a copy of property class and believe that it is by design. There is the assumption that your property class is "easy" for copy. Pleas correct me if I'm wrong. --dima
