Graph::OutArcIt Class Reference

---

Detailed Description

This iterator goes trough the outgoing 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 graph g of type Graph as follows.

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

Constructor & Destructor Documentation

OutArcIt

(

)

[inline]

Warning:

The default constructor sets the iterator to an undefined value.

OutArcIt

(

const OutArcIt &

e

)

[inline]

Copy constructor.

OutArcIt

(

Invalid

)

[inline]

Initialize the iterator to be invalid.

OutArcIt	(	const Graph &	n,
		const Node &	g
	)		[inline]

This constructor sets the iterator to the first outgoing arc of the node.

Parameters:

n	the node
g	the graph

OutArcIt	(	const Graph &	,
		const Arc &
	)		[inline]

Sets the iterator to the value of the trivial iterator. This feature necessitates that each time we iterate the arc-set, the iteration order is the same.

[inline]

Assign the iterator to the next outgoing arc of the corresponding node.
