[Lemon-user] Edge Iterator for Subgraph created with FilterEdges

[Kovács Péter]

Hi,

In your example, the type of "subgraph" is "FilterEdges<SmartGraph>", so 
you need a corresponding edge iterator:
   FilterEdges<SmartGraph>::EdgeIt
instead of
   SmartGraph::EdgeIt

I hope it helps.

Regards,
Péter Kovács
