Constructor Detail

OrderedPoint2D

public OrderedPoint2D(java.awt.geom.Point2D.Double p)

Create a new pont.

Parameters:

p -

OrderedPoint2D

public OrderedPoint2D(double x,
                      double y)

Method Detail

distanceFrom

public double distanceFrom(OrderedPoint2D aPoint)

compareTo

public int compareTo(java.lang.Object o)

Compares two points. They are ordered first by X value, then by Y value.

Specified by:

compareTo in interface java.lang.Comparable

Parameters:

o -

equals

public boolean equals(java.lang.Object o)

The points are equal if both X and Y are the same.

Overrides:

equals in class java.awt.geom.Point2D

Parameters:

o -

hashCode

public int hashCode()

X+Y*1000. Could probably be done better.

Overrides:

hashCode in class java.awt.geom.Point2D
