Class IntegerEdgeNameProvider<E>

java.lang.Object

org.jgrapht.ext.IntegerEdgeNameProvider<E>

All Implemented Interfaces:

EdgeNameProvider<E>

public class IntegerEdgeNameProvider<E>
extends Object
implements EdgeNameProvider<E>

Assigns a unique integer to represent each edge. Each instance of IntegerEdgeNameProvider maintains an internal map between every edge it has ever seen and the unique integer representing that edge. As a result it is probably desirable to have a separate instance for each distinct graph.
