Class java.awt.geom.Ellipse2D

java.lang.Object
  |
  +--java.awt.geom.RectangularShape

        +--java.awt.geom.Ellipse2D

Direct Known Subclasses:

Ellipse2D.Double, Ellipse2D.Float

public abstract class Ellipse2D

extends RectangularShape

An ellipse defined by a bounding rectangle.

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

Inner Class Summary

static	Ellipse2D.Double An ellipse specified in double precision.
static	Ellipse2D.Float An ellipse specified in float precision.

Constructor Summary

Ellipse2D()
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 Rectangle.
boolean	contains(double x, double y) Test if a given Point is inside the boundary of the shape.
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 Rectangle.
