Utilize an map (map_hash if available, or map if not) for your external property container. This way a key is needed instead of an index (which would have the problems you indicated). yg-boost-users@m.gmane.org wrote:
I have a graph which might change during it's lifetime. I want to attach external properties to this graph. Now, it seems like that in order to be able to attach external properties, I need to have an internal property with edge indices, ie that enumerates the edges. These indices need to be continuous as I gather, since they are used to index for instance a vector of num_edges() elements. Does this mean that I have to re-enumerate all edges if I remove one? This seems to me very cumbersome and also time consuming if the graph is large and changes a lot. Is there another way?
