Can you do something like

typedef boost::graph_traits<Graph>::edge_descriptor   Edge; Edge e;  .... std::set<Edge> edges; edgeSet.insert( e );

I am getting compiler errors that imply that the edge_descriptor does not implement the < operator.

Thanks,

I'm experiencing the same issue... I'd like defining an operator< for the specific edge_descriptor I have (i.e., I use boost::vecS for the edge container), but I don't know what kind of type edge_descriptor is?

Or maybe, I can safety convert an edge_descriptor to a standard type like 'int'?

I finally found the implementation of edge_descriptor in boost/graph/detail/edge.hpp Since I found that operator== use get_property method, I defined an operator < that compares results of get_property() I think it works for my graphs. But I have no idea of the limitations of this silly workaround! Hope it will be useful for someone else. Regards, -- Johan
