Class UndirectedEdgeContainer<V,​E>

  • Type Parameters:
    V - the graph vertex type
    E - the graph edge type
    All Implemented Interfaces:
    java.io.Serializable
    public class UndirectedEdgeContainer<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).
