public boolean isEmpty()
RectangularShape
is empty.
When the RectangularShape
is empty, it encloses no
area.
isEmpty
in class RectangularShape
true
if the RectangularShape
is empty;
false
otherwise.public void setFrame(double x, double y, double w, double h)

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.
