Digraph::OutArcIt Class Reference

---

Detailed Description

This iterator goes trough the outgoing arcs of a certain node of a digraph. Its usage is quite simple, for example, you can count the number of outgoing arcs of a node n in a digraph g of type Digraph as follows.

          int count=0;
          for (Digraph::OutArcIt a(g, n); a!=INVALID; ++a) ++count;
