[Lemon-user] Copy constructors

[D Haley]

Hello again,

I am having more troubles with edgemaps (thanks for the prev. help, worked a treat). Due to the library interface, the copy constructors are private for edgemaps, which seem to prevent me assigning or dupliating them in any way. Is there a way I can do something like the following? I'm currently dropping to pointer semantics, but it feels like a kludge.

        vector<lemon::ListGraph> g;
        vector<lemon::ListGraph::EdgeMap<float> > edgeCostVec;

        makeSomeGraphs(g); //pass-by-ref (non-const)

        edgeCostVec[ui].resize(g.size());
        for(unsigned int ui=0;ui<g.size(); ui++)
                edgeCostVec[ui] = (lemon::ListGraph::EdgeMap<float>(g[ui]));
