DirectedEdgeContainer (JGraphT : a free Java graph library)

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:

java.io.Serializable
```
public class DirectedEdgeContainer<V,E>
extends java.lang.Object
implements java.io.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).
