All Implemented Interfaces:

Shape, Serializable, Cloneable

public class XRectangle2D
extends Rectangle2D
implements Serializable

Serializable, high-performance double-precision rectangle. Instead of using x, y, width and height, this class store rectangle's coordinates into the following fields: xmin, xmax, ymin et ymax. Methods likes contains and intersects are faster, which make this class more appropriate for using intensively inside a loop.

public Rectangle2D createUnion(Rectangle2D rect)

Returns a new Rectangle2D object representing the union of this Rectangle2D with the specified Rectangle2D.

add

public void add(double x,

Adds a point, specified by the double precision arguments x and y, to this Rectangle2D. The resulting Rectangle2D is the smallest Rectangle2D that contains both the original Rectangle2D and the specified point.

After adding a point, a call to contains with the added point as an argument does not necessarily return true. The contains method does not return true for points on the right or bottom edges of a rectangle. Therefore, if the added point falls on the left or bottom edge of the enlarged rectangle, contains returns false for that point.

Overrides:

add in class Rectangle2D

add

public void add(Rectangle2D rect)

Adds a Rectangle2D object to this Rectangle2D. The resulting Rectangle2D is the union of the two Rectangle2D objects.

Overrides:

add in class Rectangle2D

Parameters:

rect - the Rectangle2D to add to this Rectangle2D.

toString

public String toString()

Returns the String representation of this Rectangle2D.

Overrides:
