        +--java.awt.geom.RoundRectangle2D

Direct Known Subclasses:

RoundRectangle2D.Double, RoundRectangle2D.Float

public abstract class RoundRectangle2D

extends RectangularShape

A rectangle with rounded corners defined by a location (x, y), a dimension (w x h), and the width and height of an arc to round the corners with.

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

Inner Class Summary

static	RoundRectangle2D.Double A rectangle with rounded corners all specified in double coordinates.
static	RoundRectangle2D.Float A rectangle with rounded corners all specified in float coordinates.

Constructor Summary

RoundRectangle2D()
This is an abstract class that cannot be instantiated directly.

Method Summary

boolean	contains(double x, double y, double w, double h) Test if the interior of the Shape entirely contains the given set of rectangular coordinates.
boolean	contains(double x, double y) Test if a given coordinate is inside the boundary of the shape.
abstract double	getArcHeight() Gets the height of the arc that rounds off the corners.
abstract double	getArcWidth() Gets the width of the arc that rounds off the corners.
PathIterator	getPathIterator(AffineTransform at) Return an iteration object that defines the boundary of the shape.
boolean	intersects(double x, double y, double w, double h) Test if the interior of the Shape intersects the interior of a given set of rectangular coordinates.
void	setFrame(double x, double y, double w, double h) Sets the location and size of the outer bounds of this shape to the specified rectangular values.
abstract void	setRoundRect(double x, double y, double w, double h, double arcWidth, double arcHeight) Sets the location, size, and corner radii of this rounded rectangle to the specified double values.
void	setRoundRect(RoundRectangle2D rr) Sets this rounded rectangle to be the same as the specified RoundRectangle.
