Graph::OutArcIt Class Reference

Detailed Description

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

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