All Implemented Interfaces:

Cloneable, Shape

Direct Known Subclasses:

Rectangle, Rectangle2D.Double, Rectangle2D.Float

public abstract class Rectangle2D

extends RectangularShape

The Rectangle2D class describes a rectangle defined by a location (x, y) and dimension (w x h).

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

Nested Class Summary
static class	Rectangle2D.Double     The Double class defines a rectangle specified in double coordinates.
static class	Rectangle2D.Float     The Float class defines a rectangle specified in float coordinates.

 

Field Summary
static int	OUT_BOTTOM     The bitmask that indicates that a point lies below this Rectangle2D.
static int	OUT_LEFT     The bitmask that indicates that a point lies to the left of this Rectangle2D.
static int	OUT_RIGHT     The bitmask that indicates that a point lies to the right of this Rectangle2D.
static int	OUT_TOP     The bitmask that indicates that a point lies above this Rectangle2D.

 

Constructor Summary
protected	Rectangle2D()     This is an abstract class that cannot be instantiated directly.

PathIterator	getPathIterator(AffineTransform at)     Returns an iteration object that defines the boundary of this Rectangle2D.
PathIterator	getPathIterator(AffineTransform at, double flatness)     Returns an iteration object that defines the boundary of the flattened Rectangle2D.
int	hashCode()     Returns the hashcode for this Rectangle2D.
static void	intersect(Rectangle2D src1, Rectangle2D src2, Rectangle2D dest)     Intersects the pair of specified source Rectangle2D objects and puts the result into the specified destination Rectangle2D object.
boolean	intersects(double x, double y, double w, double h)     Tests if the interior of this Rectangle2D intersects the interior of a specified set of rectangular coordinates.
boolean	intersectsLine(double x1, double y1, double x2, double y2)     Tests if the specified line segment intersects the interior of this Rectangle2D.

abstract  int	outcode(double x, double y)     Determines where the specified coordinates lie with respect to this Rectangle2D.
int	outcode(Point2D p)     Determines where the specified Point2D lies with respect to this Rectangle2D.
void	setFrame(double x, double y, double w, double h)     Sets the location and size of the outer bounds of this Rectangle2D to the specified rectangular values.
abstract  void	setRect(double x, double y, double w, double h)     Sets the location and size of this Rectangle2D to the specified double values.
void	setRect(Rectangle2D r)     Sets this Rectangle2D to be the same as the specified Rectangle2D.
static void	union(Rectangle2D src1, Rectangle2D src2, Rectangle2D dest)     Unions the pair of source Rectangle2D objects and puts the result into the specified destination Rectangle2D object.
