Class Edge

java.lang.Object
  scg.ac.ni.pmf.newgraph.graphdata.Edge

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Element

public class Edge
extends java.lang.Object
implements Element, java.lang.Cloneable, java.io.Serializable

Represents a graph edge. The edge is defined by the vertices that are connected by it. Although the edge that the class represents is not directed, the vertices are named vertex A and vertex B. However, two edges where vertices A are equal to vertices B are considered equal, to preserve the non-directionability of the edge representation.
