public boolean contains(double x,
                        double y)

Test if the coordinates lie in the shape.

Parameters:

x - the x coordinate

y - the y coordinate

Returns:

true if (x,y) lies inside the shape

Since:

1.2

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

Test if a high-precision rectangle lies completely in the shape. This is true if all points in the rectangle are in the shape, with the caveat that the operation may include high probability estimates when the actual calculation is prohibitively expensive. The Area class can be used for more precise answers.

Parameters:

x - the x coordinate of the rectangle

y - the y coordinate of the rectangle

w - the width of the rectangle, undefined results if negative

h - the height of the rectangle, undefined results if negative

Returns:

true if the rectangle is contained in this shape

Since:

1.2

public boolean contains(Point2D p)

Test if the point lie in the shape.

Parameters:

p - the high-precision point

Returns:

true if p lies inside the shape

Throws:

NullPointerException - if p is null

Since:

1.2

public boolean contains(Rectangle2D r)

Test if a high-precision rectangle lies completely in the shape. This is true if all points in the rectangle are in the shape, with the caveat that the operation may include high probability estimates when the actual calculation is prohibitively expensive. The Area class can be used for more precise answers.

Parameters:

r - the rectangle

Returns:

true if the rectangle is contained in this shape

Throws:

NullPointerException - if r is null

public Rectangle getBounds()

Returns a Rectange that bounds the shape. There is no guarantee that this is the minimum bounding box, particularly if the shape overflows the finite integer range of a bound. Generally, getBounds2D returns a tighter bound.

Returns:

the shape's bounding box

See Also:

getBounds2D()

public Rectangle2D getBounds2D()

Returns a high precision bounding box of the shape. There is no guarantee that this is the minimum bounding box, but at least it never overflows.

Returns:

the shape's bounding box

Since:

1.2

getBounds()

public PathIterator getPathIterator(AffineTransform transform)

Return an iterator along the shape boundary. If the optional transform is provided, the iterator is transformed accordingly. Each call returns a new object, independent from others in use. It is recommended, but not required, that the Shape isolate iterations from future changes to the boundary, and document this fact.

Parameters:

transform - an optional transform to apply to the iterator (null permitted).

Returns:

a new iterator over the boundary

Since:

1.2

public PathIterator getPathIterator(AffineTransform transform,
                                    double flatness)

Return an iterator along the flattened version of the shape boundary. Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE points are returned in the iterator. The flatness parameter controls how far points are allowed to differ from the real curve; although a limit on accuracy may cause this parameter to be enlarged if needed.

If the optional transform is provided, the iterator is transformed accordingly. Each call returns a new object, independent from others in use. It is recommended, but not required, that the Shape isolate iterations from future changes to the boundary, and document this fact.

Parameters:

transform - an optional transform to apply to the iterator (null permitted).

flatness - the maximum distance for deviation from the real boundary

Returns:

a new iterator over the boundary

Since:

1.2

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

Test if a high-precision rectangle intersects the shape. This is true if any point in the rectangle is in the shape, with the caveat that the operation may include high probability estimates when the actual calculation is prohibitively expensive. The Area class can be used for more precise answers.

Parameters:

x - the x coordinate of the rectangle

y - the y coordinate of the rectangle

w - the width of the rectangle, undefined results if negative

h - the height of the rectangle, undefined results if negative

Returns:

true if the rectangle intersects this shape

Since:

public boolean intersects(Rectangle2D r)

Test if a high-precision rectangle intersects the shape. This is true if any point in the rectangle is in the shape, with the caveat that the operation may include high probability estimates when the actual calculation is prohibitively expensive. The Area class can be used for more precise answers.

Parameters:

r - the rectangle

Returns:

true if the rectangle intersects this shape

Throws:

NullPointerException - if r is null
