java.awt.geom.Ellipse2D
| Ellipse2D | | abstract public class Ellipse2D extends RectangularShape (Code) | | 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.

| Ellipse2D | | protected Ellipse2D()(Code) | | 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.

| equals | | public boolean equals(Object obj)(Code) | | 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.
Parameters:
obj - an Object to be compared with thisEllipse2D. true if obj is an instanceof Ellipse2D and has the same values;false otherwise.

| getPathIterator | | public PathIterator getPathIterator(AffineTransform at)(Code) | | 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 tothe coordinates as they are returned in the iteration, ornull if untransformed coordinates are desired the PathIterator object that returns thegeometry of the outline of this Ellipse2D,one segment at a time.
