public boolean contains(Point2D p)
Tests if a specified Point2D  is inside the boundary
of the Shape, as described by the

definition of insideness.

 public boolean contains(Rectangle2D r)
Tests if the interior of the Shape entirely contains the
specified Rectangle2D.
The {@code Shape.contains()} method allows a {@code Shape}
implementation to conservatively return {@code 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 {@code Shapes} this method might
return {@code false} even though the {@code Shape} contains
the {@code Rectangle2D}.
The Area  class performs
more accurate geometric computations than most
{@code Shape} objects and therefore can be used if a more precise
answer is required.

 public boolean contains(double x,
    double y)
Tests if the specified coordinates are inside the boundary of the
Shape, as described by the

definition of insideness.

 public boolean contains(double x,
    double y,
    double w,
    double h)
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 {@code Shape.contains()} method allows a {@code Shape}
implementation to conservatively return {@code 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 {@code Shapes} this method might
return {@code false} even though the {@code Shape} contains
the rectangular area.
The Area  class performs
more accurate geometric computations than most
{@code Shape} objects and therefore can be used if a more precise
answer is required.

 public Rectangle getBounds()
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.


Note that the 
definition of insideness can lead to situations where points
on the defining outline of the {@code shape} may not be considered
contained in the returned {@code bounds} object, but only in cases
where those points are also not considered contained in the original
{@code shape}.


If a {@code point} is inside the {@code shape} according to the
 contains(point)  method, then
it must be inside the returned {@code Rectangle} bounds object
according to the  contains(point) 
method of the {@code bounds}. Specifically:


 {@code shape.contains(x,y)} requires {@code bounds.contains(x,y)}


If a {@code point} is not inside the {@code shape}, then it might
still be contained in the {@code bounds} object:


 {@code bounds.contains(x,y)} does not imply {@code shape.contains(x,y)}

 public Rectangle2D getBounds2D()
Returns a high precision and more accurate bounding box of
the Shape than the getBounds method.
Note that there is no guarantee that the returned
Rectangle2D  is the smallest bounding box that encloses
the Shape, only that the Shape lies
entirely within the indicated Rectangle2D.  The
bounding box returned by this method is usually tighter than that
returned by the getBounds method and never fails due
to overflow problems since the return value can be an instance of
the Rectangle2D that uses double precision values to
store the dimensions.


Note that the 
definition of insideness can lead to situations where points
on the defining outline of the {@code shape} may not be considered
contained in the returned {@code bounds} object, but only in cases
where those points are also not considered contained in the original
{@code shape}.


If a {@code point} is inside the {@code shape} according to the
 contains(point)  method, then it must
be inside the returned {@code Rectangle2D} bounds object according
to the  contains(point)  method of the
{@code bounds}. Specifically:


 {@code shape.contains(p)} requires {@code bounds.contains(p)}


If a {@code point} is not inside the {@code shape}, then it might
still be contained in the {@code bounds} object:


 {@code bounds.contains(p)} does not imply {@code shape.contains(p)}

 public PathIterator getPathIterator(AffineTransform at)
Returns an iterator object that iterates along the
Shape boundary and provides access to the geometry of the
Shape outline.  If an optional AffineTransform 
is specified, the coordinates returned in the iteration are
transformed accordingly.

Each call to this method returns a fresh PathIterator
object that traverses the geometry of the Shape object
independently from any other PathIterator objects in use
at the same time.

It is recommended, but not guaranteed, that objects
implementing the Shape interface isolate iterations
that are in process from any changes that might occur to the original
object's geometry during such iterations.

 public PathIterator getPathIterator(AffineTransform at,
    double flatness)
Returns an iterator object that iterates along the Shape
boundary and provides access to a flattened view of the
Shape outline geometry.

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

If an optional AffineTransform is specified,
the coordinates returned in the iteration are transformed
accordingly.

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.
Note that a limit on the accuracy of the flattened path might be
silently imposed, causing very small flattening parameters to be
treated as larger values.  This limit, if there is one, is
defined by the particular implementation that is used.

Each call to this method returns a fresh PathIterator
object that traverses the Shape object geometry
independently from any other PathIterator objects in use at
the same time.

It is recommended, but not guaranteed, that objects
implementing the Shape interface isolate iterations
that are in process from any changes that might occur to the original
object's geometry during such iterations.

 public boolean intersects(Rectangle2D r)
Tests if the interior of the Shape intersects the
interior of a specified Rectangle2D.
The {@code Shape.intersects()} method allows a {@code Shape}
implementation to conservatively return {@code 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 {@code Shapes} this method might
return {@code true} even though the {@code Rectangle2D} does not
intersect the {@code Shape}.
The Area  class performs
more accurate computations of geometric intersection than most
{@code Shape} objects and therefore can be used if a more precise
answer is required.

 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.
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 {@code Shape.intersects()} method allows a {@code Shape}
implementation to conservatively return {@code 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 {@code Shapes} this method might
return {@code true} even though the rectangular area does not
intersect the {@code Shape}.
The Area  class performs
more accurate computations of geometric intersection than most
{@code Shape} objects and therefore can be used if a more precise
answer is required.
