[jgrapht-users] Edge identity

[Yossi K <yo...@gm...>]

Hello,

   AbstractBaseGraph.containsEdge() checks whetehr edgeMap contains
   the edge in its key set.

    public boolean containsEdge(E e)
    {
        return edgeMap.containsKey(e);
    }

   When the edges are strings, this test makes it impossible for a graph
   to have two edges with the same label. For example, when the edges
   are words in a sentence and one of the words appears more than once.

  Doesn't the identity of an edge include its start and end vertices as
well?

    Thanks,
       Y
