public static class Rectangle2D.Double extends Rectangle2D implements Serializable
The Double
class defines a rectangle specified in double coordinates.
Rectangle2D.Double, Rectangle2D.Float
public double x
The X coordinate of this Rectangle2D
.
public double y
The Y coordinate of this Rectangle2D
.
public double width
The width of this Rectangle2D
.
public double height
The height of this Rectangle2D
.
public Double()
Constructs a new Rectangle2D
, initialized to location (0, 0) and size (0, 0).
public Double(double x, double y, double w, double h)
Constructs and initializes a Rectangle2D
from the specified double
coordinates.
x
- the X coordinate of the upper-left corner of the newly constructed Rectangle2D
y
- the Y coordinate of the upper-left corner of the newly constructed Rectangle2D
w
- the width of the newly constructed Rectangle2D
h
- the height of the newly constructed Rectangle2D
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 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 setRect(double x, double y, double w, double h)
Sets the location and size of this Rectangle2D
to the specified double
values.
setRect
in class Rectangle2D
x
- the X coordinate of the upper-left corner of this Rectangle2D
y
- the Y coordinate of the upper-left corner of this Rectangle2D
w
- the width of this Rectangle2D
h
- the height of this Rectangle2D
public void setRect(Rectangle2D r)
Sets this Rectangle2D
to be the same as the specified Rectangle2D
.
setRect
in class Rectangle2D
r
- the specified Rectangle2D
public int outcode(double x, double y)
Determines where the specified coordinates lie with respect to this 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
.

, Rectangle2D.OUT_BOTTOM
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)

public Rectangle2D createIntersection(Rectangle2D r)
Returns a new Rectangle2D
object representing the intersection of this Rectangle2D
with the specified Rectangle2D
.
createIntersection
in class Rectangle2D
r
- the Rectangle2D
to be intersected with this Rectangle2D
Rectangle2D
contained in both the specified Rectangle2D
and in this Rectangle2D
.public Rectangle2D createUnion(Rectangle2D r)
Returns a new Rectangle2D
object representing the union of this Rectangle2D
with the specified Rectangle2D
.
createUnion
in class Rectangle2D
r
- the Rectangle2D
to be combined with this Rectangle2D
Rectangle2D
containing both the specified Rectangle2D
and this Rectangle2D
.public String toString()
Returns the String
representation of this Rectangle2D
.
