public abstract class RoundRectangle2D extends RectangularShape
RoundRectangle2D
class defines a rectangle with
rounded corners defined by a location (x,y)
, a
dimension (w x h)
, and the width and height of an arc
with which to round the corners.
This class is the abstract superclass for all objects that store a 2D rounded rectangle. The actual storage representation of the coordinates is left to the subclass.
