in classRoundRectangle2D
 Returns:
 the width of the arc that rounds off the corners
of this
RoundRectangle2D
.  Since:

in classRectangularShape
 Returns:
true
if theRectangularShape
is empty;false

setRoundRect
public void setRoundRect(float x, float y, float w, float h, float arcw, float arch)Sets the location, size, and corner radii of thisRoundRectangle2D
to the specifiedfloat
values. Parameters:
x
 the X coordinate to which to set the location of thisRoundRectangle2D
y
 the Y coordinate to which to set the location of thisRoundRectangle2D
w
 the width to which to set thisRoundRectangle2D
h
 the height to which to set thisRoundRectangle2D
arcw
 the width to which to set the arc of thisRoundRectangle2D
arch
 the height to which to set the arc of thisRoundRectangle2D
 Since:
 1.2

setRoundRect
public void setRoundRect(double x, double y, double w, double h, double arcw, double arch)Sets the location, size, and corner radii of thisRoundRectangle2D
to the specifieddouble
values. Specified by:
setRoundRect
in classRoundRectangle2D
 Parameters:
x
 the X coordinate to which to set the location of thisRoundRectangle2D
y
 the Y coordinate to which to set the location of thisRoundRectangle2D
w
 the width to which to set thisRoundRectangle2D
h
 the height to which to set thisRoundRectangle2D
arcw
 the width to which to set the arc of thisRoundRectangle2D
arch
 the height to which to set the arc of thisRoundRectangle2D
 Since:
 1.2

setRoundRect
Sets thisRoundRectangle2D
to be the same as the specifiedRoundRectangle2D
. Overrides:
setRoundRect
in classRoundRectangle2D
 Parameters:
rr
 the specifiedRoundRectangle2D
 Since:
 1.2

getBounds2D
Returns a high precision and more accurate bounding box of theShape
than thegetBounds
method. Note that there is no guarantee that the returnedRectangle2D
is the smallest bounding box that encloses theShape
, only that theShape
lies entirely within the indicatedRectangle2D
. The bounding box returned by this method is usually tighter than that returned by thegetBounds
method and never fails due to overflow problems since the return value can be an instance of theRectangle2D
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
shape
may not be considered contained in the returnedbounds
object, but only in cases where those points are also not considered contained in the originalshape
.If a
point
is inside theshape
according to thecontains(point)
method, then it must be inside the returnedRectangle2D
bounds object according to thecontains(point)
method of thebounds
. Specifically:shape.contains(p)
requiresbounds.contains(p)
If a
point
is not inside theshape
, then it might still be contained in thebounds
object:bounds.contains(p)
does not implyshape.contains(p)
 Specified by:
getBounds2D
in interfaceShape
 Returns:
 an instance of
Rectangle2D
that is a highprecision bounding box of theShape
.  Since:
 1.2
