getArcWidth
public double getArcWidth()Gets the width of the arc that rounds off the corners.- Specified by:
getArcWidthin classRoundRectangle2D- Returns:
- the width of the arc that rounds off the corners
of this
RoundRectangle2D. - Since:

getArcHeight
public double getArcHeight()Gets the height of the arc that rounds off the corners.- Specified by:
getArcHeightin classRoundRectangle2D- Returns:
- the height of the arc that rounds off the corners
of this
RoundRectangle2D. - Since:

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
-
setRoundRect
public void setRoundRect(double x, double y, double w, double h, double arcw, double arch) Sets the location, size, and corner radii of thisRoundRectangle2Dto the specifieddoublevalues.- Specified by:
setRoundRectin classRoundRectangle2D- Parameters:
x- the X coordinate to which to set the location of thisRoundRectangle2Dy- the Y coordinate to which to set the location of thisRoundRectangle2Dw- the width to which to set thisRoundRectangle2Dh- the height to which to set thisRoundRectangle2Darcw- the width to which to set the arc of thisRoundRectangle2Darch- the height to which to set the arc of thisRoundRectangle2D- Since:
- 1.2
-
setRoundRect
Sets thisRoundRectangle2Dto be the same as the specifiedRoundRectangle2D.- Overrides:
setRoundRectin classRoundRectangle2D- Parameters:
rr- the specifiedRoundRectangle2D- 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
