Hello, I have a graph representing the Network topology and I want to replace it by a BGL graph. My problem is that I need to find a vertex by its IP address (an internal property), but I think we can only find a vertex with its vertex_descriptor. A solution is to maintain a map from IP address to vertex_descriptor. But removing a vertex with vecS for VertexList invalidates all vertex descriptors. Unfortunately, I need some efficiently to find a vertex, so listS seems not appropriated. Finally, I try to use setS for VertexList (and it works IMHO), but in the documentation: "The container must model Sequence or RandomAccessContainer." Hence, my questions are: - Can I use setS for VertexList ? And if I can't, why ? - Is there a better solution to find vertex by an internal property that handle an exterior map ? Cheers, -- Johan
