Graph::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 Graph as follows:

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