[jgrapht-users] List all edges

[Federico F. <fed...@gm...>]

Hi all,
suppose that I have a graph g2, and I get the set of all edges, e.g.:
Set es = g2.edgeSet();
I tried to print the edges, via the routine:
Iterator itEdge = es.iterator();

while (itEdge.hasNext()){
            Edge de = (Edge) itEdge.next();
            System.out.println(" next edge   "+de.toString());
}

and I get all "null" as printed values, although es.size() does return the
correct number of edges.

Is there a way to list all the edges correctly ?

Many thanks,
Federico
