java.awt.geom
class Ellipse2D

java.lang.Object extended by java.awt.geom.RectangularShape extended by java.awt.geom.Ellipse2D
All Implemented Interfaces:
Shape, Cloneable
Direct Known Subclasses:
Ellipse2D.Double, Ellipse2D.Float
public abstract class Ellipse2D
extends RectangularShape

The Ellipse2D class describes an ellipse that is defined by a framing 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.

Nested Class Summary
static class
Ellipse2D.Double

           The Double class defines an ellipse specified in double precision.
static class
Ellipse2D.Float

           The Float class defines an ellipse specified in float precision.
 
Constructor Summary

Constructor Detail

Ellipse2D

protected Ellipse2D()
This is an abstract class that cannot be instantiated directly. Type-specific implementation subclasses are available for instantiation and provide a number of formats for storing the information necessary to satisfy the various accessor methods below.

Method Detail

contains

public boolean contains(double x,
                        double y)
{@inheritDoc}

Parameters:
x
y

contains

public boolean contains(double x,
                        double y,
                        double w,
                        double h)
{@inheritDoc}

Parameters:
x
y
w
h

equals

public boolean equals(Object obj)
Determines whether or not the specified Object is equal to this Ellipse2D. The specified Object is equal to this Ellipse2D if it is an instance of Ellipse2D and if its location and size are the same as this Ellipse2D.

Overrides:
equals in class Object
Parameters:
obj - an Object to be compared with this Ellipse2D.
Returns:
true if obj is an instance of Ellipse2D and has the same values; false otherwise.

getPathIterator

public PathIterator getPathIterator(AffineTransform at)
Returns an iteration object that defines the boundary of this Ellipse2D. The iterator for this class is multi-threaded safe, which means that this Ellipse2D class guarantees that modifications to the geometry of this Ellipse2D object do not affect any iterations of that geometry that are already in process.

Parameters:
at - an optional AffineTransform to be applied to the coordinates as they are returned in the iteration, or null if untransformed coordinates are desired
Returns:
the PathIterator object that returns the geometry of the outline of this Ellipse2D, one segment at a time.

hashCode

public int hashCode()
Returns the hashcode for this Ellipse2D.

Overrides:
hashCode in class Object
Returns:
the hashcode for this Ellipse2D.

intersects

public boolean intersects(double x,
                          double y,
                          double w,
                          double h)
{@inheritDoc}

Parameters:
x
y
w
h
