Re: [Boost-users] BGL - changing internal values of a graph

Hi Renato,

The sequence of statements:

Edge e; e = graph[pred]; e.count++;

copies the Edge structure from graph[pred] to e by value, then makes a modification to the copy in e, which is then thrown away when e goes out of scope. Instead, try:

graph[pred].count++;

Oh my, that obviously worked! Thanks! It's the kind of silly things that you need someone else to show you... ;) Thank you! --renato
