Class Point

java.lang.Object
  com.sun.lwuit.geom.Point

public class Point

extends Object

A point representing a location in (x, y) coordinate space, specified in integer precision.

Constructor Summary

Point()
Constructs and initializes a point at the origin (0, 0) of the coordinate space.

Point(int x, int y)
Constructs and initializes a point at the specified (x, y) location in the coordinate space.

Point(Point p)
Constructs and initializes a point with the same location as the specified Point object.

Method Summary

Object	clone() Creates a new object of the same class and with the same contents as this object.
boolean	equals(Object obj) Determines whether or not two points are equal.
Point	getLocation() Returns the location of this point.
int	hashCode() Returns the hashcode for this Point.
void	move(int x, int y) Moves this point to the specified location in the (x, y) coordinate plane.
void	setLocation(int x, int y) Changes the point to have the specified location.
void	setLocation(Point p) Sets the location of the point to the specified location.
String	toString() Returns a string representation of this point and its location in the (x, y) coordinate space.
void	translate(int dx, int dy) Translates this point, at location (x, y), by dx along the x axis and dy along the y axis so that it now represents the point (x + dx, y + dy).

Constructor Detail

Point

public Point()

Constructs and initializes a point at the origin (0, 0) of the coordinate space.

Point

public Point(int x,
             int y)

Constructs and initializes a point at the specified (x, y) location in the coordinate space.

Parameters:

x - the x coordinate

y - the y coordinate

Point

public Point(Point p)

Constructs and initializes a point with the same location as the specified Point object.

Parameters:

p - the specified Point object

Method Detail

clone

public Object clone()

Creates a new object of the same class and with the same contents as this object.

Returns:

the new Point

equals

public boolean equals(Object obj)

Determines whether or not two points are equal.

Parameters:

obj - the Point to be compared to

Returns:

true if points are equal, false otherwise

getLocation

public Point getLocation()

Returns the location of this point.

Returns:

the location

See Also:

setLocation(int, int)

hashCode

public int hashCode()

Returns the hashcode for this Point.

Returns:

the hashcode

move

public void move(int x,
                 int y)

Moves this point to the specified location in the (x, y) coordinate plane.

Parameters:

x - x coordinate of the specified location

y - y coordinate of the specified location

setLocation

public void setLocation(int x,
                        int y)

Changes the point to have the specified location.

Parameters:

x - x coordinate of the specified location

y - y coordinate of the specified location

See Also:

getLocation()

setLocation

public void setLocation(Point p)

Sets the location of the point to the specified location.

Parameters:

p - the Point of the specified location

getLocation()

toString

public String toString()

Returns a string representation of this point and its location in the (x, y) coordinate space.

Returns:

the String representation

translate

public void translate(int dx,
                      int dy)

Translates this point, at location (x, y), by dx along the x axis and dy along the y axis so that it now represents the point (x + dx, y + dy).

Parameters:

dx - translation value in x direction

dy - translation value in y direction
