Class EdgeData

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

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable, ElementData

public final class EdgeData
extends java.lang.Object
implements ElementData, java.io.Serializable, java.lang.Cloneable, java.lang.Comparable

Represents the data which defines an edge. It has the IDs of the both vertices and the multiplicity of the edge. It also implements the basic methods for manipulating edges as the data structure, such as hash tables and sorting algorithms.

The class can only report info about the edge, it can not change it. For changing the edge, the class Edge is used.
