Digraph::NodeIt Class Reference

Detailed Description

This iterator goes through each node of the digraph. Its usage is quite simple, for example, you can count the number of nodes in a digraph g of type Digraph like this:

*  int count=0;
*  for (Digraph::NodeIt n(g); n!=INVALID; ++n) ++count;
* 

#include <lemon/concepts/digraph.h>
