Double
public Double()Constructs a newEllipse2D, initialized to location (0, 0) and size (0, 0).- Since:
- 1.2
-
Double
public Double(double x, double y, double w, double h) Constructs and initializes anEllipse2Dfrom the specified coordinates.- Parameters:
x- the X coordinate of the upper-left corner of the framing rectangley- the Y coordinate of the upper-left corner of the framing rectanglew- the width of the framing rectangleh- the height of the framing rectangle- Since:

Method Details
-
getX
public double getX()Returns the X coordinate of the upper-left corner of the framing rectangle indoubleprecision.- Specified by:
getXin classRectangularShape- Returns:
- the X coordinate of the upper-left corner of the framing rectangle.
- Since:
- 1.2
-
getY
public double getY()Returns the Y coordinate of the upper-left corner of the framing rectangle indoubleprecision.- Specified by:
getYin classRectangularShape- Returns:
- the Y coordinate of the upper-left corner of the framing rectangle.
- Since:
- 1.2
-
getWidth
public double getWidth()Returns the width of the framing rectangle indoubleprecision.- Specified by:
getWidthin classRectangularShape- Returns:
- the width of the framing rectangle.
- Since:
- 1.2
-
getHeight
public double getHeight()Returns the height of the framing rectangle indoubleprecision.- Specified by:
getHeightin classRectangularShape- Returns:
- the height of the framing rectangle.
- Since:
- 1.2
-
isEmpty
public boolean isEmpty()Determines whether theRectangularShapeis empty. When theRectangularShapeis empty, it encloses no area.- Specified by:
isEmptyin classRectangularShape- Returns:
trueif theRectangularShapeis empty;falseotherwise.- Since:
- 1.2

setFrame
public void setFrame(double x, double y, double w, double h) Sets the location and size of the framing rectangle of thisShapeto the specified rectangular values.- Specified by:
setFramein classRectangularShape- Parameters:
x- the X coordinate of the upper-left corner of the specified rectangular shapey- the Y coordinate of the upper-left corner of the specified rectangular shapew- the width of the specified rectangular shapeh- the height of the specified rectangular shape- Since:
- 1.2

getBounds2D
Returns a high precision and more accurate bounding box of theShapethan thegetBoundsmethod. Note that there is no guarantee that the returnedRectangle2Dis the smallest bounding box that encloses theShape, only that theShapelies entirely within the indicatedRectangle2D. The bounding box returned by this method is usually tighter than that returned by thegetBoundsmethod and never fails due to overflow problems since the return value can be an instance of theRectangle2Dthat 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
shapemay not be considered contained in the returnedboundsobject, but only in cases where those points are also not considered contained in the originalshape.If a
pointis inside theshapeaccording to thecontains(point)method, then it must be inside the returnedRectangle2Dbounds object according to thecontains(point)method of thebounds. Specifically:shape.contains(p)requiresbounds.contains(p)If a
pointis not inside theshape, then it might still be contained in theboundsobject:bounds.contains(p)does not implyshape.contains(p)- Specified by:
getBounds2Din interfaceShape- Returns:
- an instance of
Rectangle2Dthat is a high-precision bounding box of theShape. - Since:
- 1.2
