Module org.jgrapht.core

Package org.jgrapht.graph.specifics

Class UndirectedEdgeContainer<V,E>

java.lang.Object

org.jgrapht.graph.specifics.UndirectedEdgeContainer<V,E>

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Implemented Interfaces:

Serializable

public class UndirectedEdgeContainer<V,E>
extends Object
implements Serializable

A container for vertex edges.

In this edge container we use array lists to minimize memory toll. However, for high-degree vertices we replace the entire edge container with a direct access subclass (to be implemented).
