Interface Edge<V extends Vertex>

Type Parameters:

V - the Graph vertices type

All Known Subinterfaces:

LabeledEdge<V>, LabeledWeightedEdge<V>, WeightedEdge<V>

public interface Edge<V extends Vertex>

An Edge is the link that connect a pair of Vertex. A Graph in which Edges have no orientation, Vertex members are not ordered pairs. In a DirectedGraph, Edges have orientation, so relation expressed by the Edge has to be intended from getHead() to getTail().

Method Summary

V	getHead() Return the head of this edge.
V	getTail() Return the tail of this edge.

getHead

V getHead()

Return the head of this edge.

Returns:

the head of this edge.

getTail

V getTail()

Return the tail of this edge.

Returns:

the tail of this edge.
