double
precision.
getY
in class RectangularShape
public double getWidth()
double
precision.

in class RectangularShape
public double getHeight()
double
precision.
getHeight
in class RectangularShape
public boolean isEmpty()
RectangularShape
is empty.
When the RectangularShape
is empty, it encloses no
area.

if the RectangularShape
is empty;
false
otherwise.public void setRect(double x, double y, double w, double h)
Rectangle2D
to the specified double
values.
setRect
in class Rectangle2D

- the Y coordinate of the upper-left corner
of this Rectangle2D
w
- the width of this Rectangle2D

- the height of this Rectangle2D
public void setRect(Rectangle2D r)
Rectangle2D
to be the same as the specified
Rectangle2D
.
setRect
in class Rectangle2D
r
- the specified Rectangle2D
public int outcode(double x, double y)
Rectangle2D
.
This method computes a binary OR of the appropriate mask values
indicating, for each side of this Rectangle2D
,
whether or not the specified coordinates are on the same side
of the edge as the rest of this Rectangle2D
.
outcode
in class Rectangle2D
x
- the specified X coordinatey
- the specified Y coordinate

Rectangle2D.OUT_BOTTOM
public Rectangle2D getBounds2D()
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.
