public class Edges

extends Object

An iterator over a set of edges. Objects of this class generate edges one at a time. Successive calls to the next method return successive edges from the set.

The canonical way to process the edges of graph G is as follows:

 for (Edges E= G.edges(); E.hasNext(); )
	     { Edge e= E.next();
	       handle(e);
	     }
	     

Method Summary

boolean	hasNext() Returns true if there are any edges left.
Edge	next() Returns the next edge.
