Class DirectedEdgeContainer<V,E>

java.lang.Object
org.jgrapht.graph.specifics.DirectedEdgeContainer<V,E>
Type Parameters:
V - the graph vertex type
E - the graph edge type
All Implemented Interfaces:
Serializable
public class DirectedEdgeContainer<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).
