public abstract class Rectangle2D
extends RectangularShape
A rectangle defined by a location (x, y) and dimension (w x h).

This class is only the abstract superclass for all objects which store a 2D rectangle. The actual storage representation of the coordinates is left to the subclass.

Class Index

o Rectangle2D.Double
A rectangle specified in double coordinates.
o Rectangle2D.Float
A rectangle specified in float coordinates.

Variable Index

o OUT_BOTTOM
The bitmask which indicates that a point lies below this Rectangle.
o OUT_LEFT
The bitmask which indicates that a point lies to the left of this Rectangle.
o OUT_RIGHT
The bitmask which indicates that a point lies to the right of this Rectangle.
o OUT_TOP
The bitmask which indicates that a point lies above this Rectangle.

Constructor Index

o Rectangle2D()

OUT_LEFT, OUT_TOP, OUT_RIGHT, OUT_BOTTOM
o outcode 
public int outcode(Point2D p)
Determines where the specified point lies with respect to this Rectangle. This method computes a binary OR of the appropriate mask values indicating which sides of the rectangle the given point is outside of.

Returns:
the logical OR of all appropriate out codes
