Re: [Boost-users] BGL: Get a bundled property for a particular edge_descriptor

Consider this setup:

struct MyProperty { int MyIntProperty; };

typedef adjacency_list Graph;

Graph g;

Graph::vertex_descriptor v0 = add_vertex(g); Graph::vertex_descriptor v1 = add_vertex(g); Graph::vertex_descriptor v2 = add_vertex(g);

std::pair e01 = add_edge(v0, v1, g);

Now I want to get the bundled propery corresponding to e01. I tried this:

property_map::type MyIntPropertyMap = get(&MyProperty::MyIntProperty, g); cout << MyIntPropertyMap[e01.first];

Try g[e01.first].MyIntProperty for direct access; if you want to use get() with a separate property map, you will need to use the non-bundled syntax "cout << get(MyIntPropertyMap, e01.first);". -- Jeremiah Willcock
