Constructor Detail

RoundRectangle2D

protected RoundRectangle2D()

Create a RoundRectangle2D. This is protected because this class is abstract and cannot be instantiated.

Method Detail

getArcHeight

public abstract double getArcHeight()

Return the arc height of this round rectangle. The arc height and width control the roundness of the corners of the rectangle.

Returns:

The arc height.

See Also:

getArcWidth()

getArcWidth

public abstract double getArcWidth()

Return the arc width of this round rectangle. The arc width and height control the roundness of the corners of the rectangle.

Returns:

The arc width.
