All Implemented Interfaces:

java.util.Collection, java.util.List, java.util.Set

public class UndirectedEdgeList

extends com.tensegrity.graph.model.AbstractEdgeList

implements java.util.Set, java.util.List

Special set that eliminates back edges. If you add an edge and a backedge to this set then only one is kept. The whole concept is to eliminate double edges as they should not appear in undirected graphs.
