ArcIt Class Reference


Detailed Description

This iterator goes through each arc of the digraph. Its usage is quite simple, for example, you can count the number of arcs in a digraph g of type Digraph as follows:
          int count=0;
          for(Digraph::ArcIt a(g); a!=INVALID; ++a) ++count;
#include <lemon/concepts/digraph.h>
