  mathcomp.gridgeom.Edge

All Implemented Interfaces:

java.lang.Comparable, Geometric

public class Edge
extends java.lang.Object
implements java.lang.Comparable, Geometric

An edge consists of two Nodes and (at most) two adjacent Triangles. The implementation of Object.hashCode() depends on Commons Lang.
