Constructor Detail

MyRectangle

public MyRectangle()

Constructs a new Rectangle whose top-left corner is at (0, 0) in the coordinate space, and whose width and height are both zero.

MyRectangle

public MyRectangle(Rectangle r)

Constructs a new Rectangle, initialized to match the values of the specified Rectangle.

Parameters:

r - the Rectangle from which to copy initial values to a newly constructed Rectangle

Since:

JDK1.1

MyRectangle

public MyRectangle(int x,
                   int y,
                   int width,
                   int height)

Constructs a new Rectangle whose top-left corner is specified as (x, y) and whose width and height are specified by the arguments of the same name.

Parameters:

x - the specified x coordinate

y - the specified y coordinate

width - the width of the Rectangle

height - the height of the Rectangle

MyRectangle

public MyRectangle(int width,
                   int height)

Constructs a new Rectangle whose top-left corner is at (0, 0) in the coordinate space, and whose width and height are specified by the arguments of the same name.

Parameters:

width - the width of the Rectangle

height - the height of the Rectangle

MyRectangle

public MyRectangle(Point p,
                   Dimension d)

Constructs a new Rectangle whose top-left corner is specified by the Point argument, and whose width and height are specified by the Dimension argument.

Parameters:

p - a Point that is the top-left corner of the Rectangle

d - a Dimension, representing the width and height of the Rectangle

MyRectangle

public MyRectangle(Point p)

Constructs a new Rectangle whose top-left corner is the specified Point, and whose width and height are both zero.

Parameters:

p - a Point that is the top left corner of the Rectangle

MyRectangle

public MyRectangle(Dimension d)

Constructs a new Rectangle whose top left corner is (0, 0) and whose width and height are specified by the Dimension argument.

Parameters:

d - a Dimension, specifying width and height

MyRectangle

public MyRectangle(String desc)

Constrcuts a new rectangle from a string like '300,200;20x40'. Throws an IllegalArgumentException if parsing fails.

Method Detail

parseRectangle

public static Rectangle parseRectangle(String desc)

Parses a point from a String. Throws an IllegalArgumentException if parsing fails.

toString

public static String toString(Rectangle p)

Overrides the string representation. Here, output is reduced to a simple four-integer string, like '300,200;20x40'. The output string is feasable for direct-passing it to the constructor of this class. The static version also works with the original Rectangle class.

toString

public String toString()

Overrides the string representation. Here, output is reduced to a simple four-integer string, like '300,200;20x40'. The output string is feasable for direct-passing it to the constructor of this class.

Overrides:

toString in class Rectangle

distanceToEdge

public double distanceToEdge(Point2D inside)

Returns the distance of this pixel to the closest edge. If the pixel is outside, -1 is returned. If the rectangle is null, also -1 is returned.

distanceToEdge

public static double distanceToEdge(Rectangle2D rec,
                                    Point2D inside)

Returns the distance of this pixel to the closest edge. If the pixel is outside, -1 is returned. If the rectangle is null, also -1 is returned.
