BpGraph::RedNodeIt Class Reference

Detailed Description

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

*  int count=0;
*  for (BpGraph::RedNodeIt n(g); n!=INVALID; ++n) ++count;
* 

#include <lemon/concepts/bpgraph.h>
