Class IntegerNameProvider<V>

java.lang.Object

org.jgrapht.ext.IntegerNameProvider<V>

All Implemented Interfaces:

VertexNameProvider<V>

public class IntegerNameProvider<V>
extends Object
implements VertexNameProvider<V>

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