public abstract class Point

extends java.lang.Object

implements java.lang.Cloneable

Point is an abstract class which can be used to store any dimensional system. A mathematical operation on a Point; add, multiply, and abs, can be performed using instance or static methods.

Method Summary

abstract void	abs() Instance method to calculate the absolute value of the Point, abstract and must be defined by any subclasses of Point.
static Point	abs(Point p) Static method to calculate and return a new Point equal to the absolute value of the Point p.
abstract void	add(Point delta) Instance method to add a Point to the current Point, abstract and must be defined by any subclasses of Point.
static Point	add(Point a, Point b) Static method to add two Points.
static Point	add(Point a, Point b, Point c) Static method to add three Points.
static Point	add(Point a, Point b, Point c, Point d) Static method to add four Points.
java.lang.Object	clone() Overrides the object.clone() method to enable Point cloning outside of Point package.
abstract double	coordinate(int i) Instance method to return the coordinate of the Point at index i, abstract and must be defined by any subclasses of Point.
abstract int	dimension() Instance method to return the dimension of the Point, abstract and must be defined by any subclasses of Point.
abstract double	max() Method to return the maximum of the Point, abstract and must be defined by any subclasses of Point.
abstract double	min() Method to return the minimum of the Point, abstract and must be defined by any subclasses of Point.
abstract void	multiply(double c) Instance method to multiply the current Point by a double, abstract and must be defined by any subclasses of Point.
static Point	multiply(Point p, double c) Static method to multiply a Point by a double.
abstract void	round(int n) Instance method to round the Point's accuracy to n decimal places, abstract and must be defined by any subclasses of Point.
abstract java.lang.String	toString() Instance method to return the contents of the Point in human readable form, abstract and must be defined by any subclasses of Point.
abstract void	truncate(int n) Instance method to truncate the Point's accuracy to n decimal places, abstract and must be defined by any subclasses of Point.
