NodeIt Class Reference

---

Detailed Description

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

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

#include <lemon/concepts/bpugraph.h>

Constructor & Destructor Documentation

NodeIt

(

)

[inline]

Warning:

The default constructor sets the iterator to an undefined value.

NodeIt

(

const NodeIt &

n

)

[inline]

Copy constructor.

NodeIt

(

Invalid

)

[inline]

Initialize the iterator to be invalid.

See also:

Invalid for more details.

NodeIt

(

const BpUGraph &

)

[inline]

Sets the iterator to the first node of g.

NodeIt	(	const BpUGraph &	,
		const Node &
	)			[inline]

Sets the iterator to the node of the graph pointed by the trivial iterator. This feature necessitates that each time we iterate the edge-set, the iteration order is the same.
