Constructor and Description 

RoundRectangle2D.Double()
Constructs a new
RoundRectangle2D , initialized to
location (0.0, 0.0), size (0.0, 0.0), and corner arcs
of radius 0.0. 
RoundRectangle2D.Double(double x,
double y,
double w,
double h,
double arcw,
double arch)
Constructs and initializes a
RoundRectangle2D
from the specified double coordinates. 
Modifier and Type  Method and Description 

double 
getArcHeight()
Gets the height of the arc that rounds off the corners.

double 
getArcWidth()
Gets the width of the arc that rounds off the corners.

Rectangle2D 
getBounds2D()
Returns a high precision and more accurate bounding box of
the
Shape than the getBounds method. 
double 
getHeight()

double precision. 
double 
getX()
Returns the X coordinate of the upperleft corner of
the framing rectangle in
double precision. 
double 
getY()
Returns the Y coordinate of the upperleft corner of
the framing rectangle in
double precision. 
boolean 
isEmpty()
Determines whether the
RectangularShape is empty. 
void 
setRoundRect(double x,
double y,

RoundRectangle2D to the specified
double values. 
void 
setRoundRect(RoundRectangle2D rr)
Sets this
RoundRectangle2D to be the same as the
specified RoundRectangle2D .

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.
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 returned bounds
object, but only in cases
where those points are also not considered contained in the original
shape
.
If a point
is inside the shape
according to the
contains(point)
method, then it must
be inside the returned Rectangle2D
bounds object according
to the contains(point)
method of the
bounds
. Specifically:
shape.contains(p)
requires bounds.contains(p)
If a point
is not inside the shape
, then it might
still be contained in the bounds
object:
bounds.contains(p)
does not imply shape.contains(p)
getBounds2D
in interface Shape
Rectangle2D
that is a
highprecision bounding box of the Shape
