The width of this RoundRectangle2D.
public double height
The height of this RoundRectangle2D.
public double arcwidth
The width of the arc that rounds off the corners.
public double archeight
The height of the arc that rounds off the corners.
public Double()
Constructs a new RoundRectangle2D, initialized to location (0.0, 0.0), size (0.0, 0.0), and corner arcs of radius 0.0.
public Double(double x,
double y,
double w,
double h,
double arcw,
double arch) Constructs and initializes a RoundRectangle2D from the specified double coordinates.
x - the X coordinate of the newly constructed RoundRectangle2D
y - the Y coordinate of the newly constructed RoundRectangle2D
w - the width to which to set the newly constructed RoundRectangle2D
h - the height to which to set the newly constructed RoundRectangle2D
arcw - the width of the arc to use to round off the corners of the newly constructed RoundRectangle2D
arch - the height of the arc to use to round off the corners of the newly constructed RoundRectangle2D
public double getX()
Returns the X coordinate of the upper-left corner of the framing rectangle in double precision.
getX in class RectangularShape
public double getY()
Returns the Y coordinate of the upper-left corner of the framing rectangle in double precision.
getY in class RectangularShape
public double getWidth()
Returns the width of the framing rectangle in double precision.
getWidth in class RectangularShape
public double getHeight()
Returns the height of the framing rectangle in double precision.
getHeight in class RectangularShape
public double getArcWidth()
Gets the width of the arc that rounds off the corners.
getArcWidth in class RoundRectangle2D
RoundRectangle2D.public double getArcHeight()
Gets the height of the arc that rounds off the corners.
getArcHeight in class RoundRectangle2D
RoundRectangle2D.public boolean isEmpty()
Determines whether the 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 setRoundRect(double x,
double y,
double w,
double h,
double arcw,
double arch) Sets the location, size, and corner radii of this RoundRectangle2D to the specified double values.
setRoundRect in class RoundRectangle2D
x - the X coordinate to which to set the location of this RoundRectangle2D
y - the Y coordinate to which to set the location of this RoundRectangle2D
w - the width to which to set this RoundRectangle2D
h - the height to which to set this RoundRectangle2D
arcw - the width to which to set the arc of this RoundRectangle2D
arch - the height to which to set the arc of this RoundRectangle2D
public void setRoundRect(RoundRectangle2D rr)
Sets this RoundRectangle2D to be the same as the specified RoundRectangle2D.
setRoundRect in class RoundRectangle2D
rr - the specified RoundRectangle2D
public Rectangle2D getBounds2D()
Returns a high precision and more accurate bounding box of the 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 high-precision bounding box of the Shape.Shape.getBounds()
