BpGraph::ArcIt Class Reference

Detailed Description

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

* int count=0;
* for(BpGraph::ArcIt a(g); a!=INVALID; ++a) ++count;
*

#include <lemon/concepts/bpgraph.h>
