BpGraph::EdgeIt Class Reference

Detailed Description

This iterator goes through each edge of the graph. Its usage is quite simple, for example, you can count the number of edges in a graph g of type BpGraph as follows:

int count=0;
for(BpGraph::EdgeIt e(g); e!=INVALID; ++e) ++count;

#include <lemon/concepts/bpgraph.h>
