Class IntersectionPoint

java.lang.Object

java.awt.geom.Point2D

java.awt.geom.Point2D.Double

org.jhotdraw8.geom.intersect.IntersectionPoint

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

IntersectionPointEx

public class IntersectionPoint
extends Point2D.Double

Provides the coordinates and the argument value of one intersecting function at an intersection point.

This class extends Point2D.Double rather than aggregating it to reduce pointer chasing. As a consequence, IntersectionPoint only uses the x and y coordinates for equals and hashCode.
