java.lang.Objectjava.awt.geom.RectangularShape
java.awt.geom.Ellipse2D
The Ellipse2D class describes an ellipse that is 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.
| 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 | |
protected |
Ellipse2D()
This is an abstract class that cannot be instantiated directly. |
| Method Summary | |
boolean |
contains(double x,
double y)
Tests if a specified point is inside the boundary of this Ellipse2D. |
boolean |
contains(double x,
double y,
double w,
double h)
Tests if the interior of this Ellipse2D entirely
contains the specified rectangular area. |
PathIterator |
getPathIterator(AffineTransform at)
Returns an iteration object that defines the boundary of this Ellipse2D. |
boolean |
intersects(double x,
double y,
double w,
double h)
Tests if the interior of this Ellipse2D intersects
the interior of a specified rectangular area. |

public boolean contains(double x,
double y)
Ellipse2D.
x - the specified x coordinatey - the specified y coordinate
true if the specified point is contained
in this ellipse; false otherwise.
public boolean intersects(double x,
double y,
double w,
double h)
Ellipse2D intersects
the interior of a specified rectangular area.
w - the width of the specified rectangular areah - the height of the specified rectangluar areax - the x coordinate of the specified rectangular areay - the y coordinate of the specified rectangular area
true if this Ellipse2D contains
the specified rectangular area; false otherwise.Area
public boolean contains(double x,
double y,
double w,
double h)
Ellipse2D entirely
contains the specified rectangular area.
w - the width of the specified rectangular areah - the height of the specified rectangular areax - the x coordinate of the specified rectangular areay - the y coordinate of the specified rectangular area
true if this Ellipse2D contains
the specified rectangular area; false otherwise.Area,
Shape.intersects(double, double, double, double)public PathIterator getPathIterator(AffineTransform at)
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.
at - an optional AffineTransform to be applied to
the coordinates as they are returned in the iteration, or
null if untransformed coordinates are desired
PathIterator object that returns the
geometry of the outline of this Ellipse2D,
one segment at a time.
