public Object clone () [Inherited From RectangularShape]

Creates a new object of the same class and with the same contents as this object.

public boolean contains (double x, double y)

Tests if the specified coordinates are inside the boundary of the Shape.

Tests if the specified coordinates are inside the boundary of the
Shape.
Since: 1.2

public boolean contains (double x, double y, double w, double h)

Tests if the interior of the Shape entirely contains the specified rectangular area.

Tests if the interior of the Shape entirely contains the specified rectangular area. All coordinates that lie inside the rectangular area must lie within the Shape for the entire rectanglar area to be considered contained within the Shape.

The Shape.contains() method allows a Shape implementation to conservatively return false when:

the intersect method returns true and
the calculations to determine whether or not the Shape entirely contains the rectangular area are prohibitively expensive.

This means that for some Shapes this method might return false even though the Shape contains the rectangular area. The Area class performs more accurate geometric computations than most Shape objects and therefore can be used if a more precise answer is required.
Since: 1.2

public boolean contains (Point2D p) [Inherited From RectangularShape]

Tests if a specified Point2D is inside the boundary of the Shape.

Tests if a specified Point2D is inside the boundary
of the Shape.
Since: 1.2

public boolean contains (Rectangle2D r) [Inherited From RectangularShape]

Tests if the interior of the Shape entirely contains the specified Rectangle2D.

Tests if the interior of the Shape entirely contains the
specified Rectangle2D.
The Shape.contains() method allows a Shape
implementation to conservatively return false when:

the intersect method returns true and
the calculations to determine whether or not the
Shape entirely contains the Rectangle2D
are prohibitively expensive.

This means that for some Shapes this method might
return false even though the Shape contains
the Rectangle2D.
The Area class performs
more accurate geometric computations than most
Shape objects and therefore can be used if a more precise
answer is required.
Since: 1.2

public boolean equals (Object obj)

Determines whether or not the specified Object is equal to this Ellipse2D.

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.
Returns: true if obj is an instance of Ellipse2D and has the same values; false otherwise.

Since: 1.6

public Rectangle getBounds () [Inherited From RectangularShape]

Returns an integer Rectangle that completely encloses the Shape.

Returns an integer Rectangle that completely encloses the
Shape. Note that there is no guarantee that the
returned Rectangle is the smallest bounding box that
encloses the Shape, only that the Shape
lies entirely within the indicated Rectangle. The
returned Rectangle might also fail to completely
enclose the Shape if the Shape overflows
the limited range of the integer data type. The
getBounds2D method generally returns a
tighter bounding box due to its greater flexibility in
representation.
Since: 1.2

modifications to the geometry of this Ellipse2D
object do not affect any iterations of that geometry that
are already in process.
Returns: the PathIterator object that returns the geometry of the outline of this Ellipse2D, one segment at a time.
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
Since: 1.2

public PathIterator getPathIterator (AffineTransform at, double flatness) [Inherited From RectangularShape]

Returns an iterator object that iterates along the Shape object's boundary and provides access to a flattened view of the outline of the Shape object's geometry.

Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types will be returned by the iterator.

The amount of subdivision of the curved segments is controlled by the flatness parameter, which specifies the maximum distance that any point on the unflattened transformed curve can deviate from the returned flattened path segments. An optional AffineTransform can be specified so that the coordinates returned in the iteration are transformed accordingly.
Returns: a PathIterator object that provides access to the Shape object's flattened geometry.
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.

public boolean intersects (double x, double y, double w, double h)

Tests if the interior of the Shape intersects the interior of a specified rectangular area.

Tests if the interior of the Shape intersects the interior of a specified rectangular area. The rectangular area is considered to intersect the Shape if any point is contained in both the interior of the Shape and the specified rectangular area.

The Shape.intersects() method allows a Shape implementation to conservatively return true when:

there is a high probability that the rectangular area and the Shape intersect, but
the calculations to accurately determine this intersection are prohibitively expensive.

This means that for some Shapes this method might return true even though the rectangular area does not intersect the Shape. The Area class performs more accurate computations of geometric intersection than most Shape objects and therefore can be used if a more precise answer is required.
Since: 1.2

public boolean intersects (Rectangle2D r) [Inherited From RectangularShape]

The Shape.intersects() method allows a Shape
implementation to conservatively return true when:

there is a high probability that the Rectangle2D and the
Shape intersect, but
the calculations to accurately determine this intersection
are prohibitively expensive.

This means that for some Shapes this method might
return true even though the Rectangle2D does not
intersect the Shape.
The Area class performs
more accurate computations of geometric intersection than most
Shape objects and therefore can be used if a more precise
answer is required.
