```
    Description copied from interface: GraphicContext
    
    Draws the outline of a circular or elliptical arc covering the specified rectangle.
    The resulting arc begins at startAngle and extends for arcAngle degrees, using the current color. Angles are interpreted such that 0 degrees is at the 3 o'clock position. A positive value indicates a counter-clockwise rotation while a negative value indicates a clockwise rotation.
    The center of the arc is the center of the rectangle whose origin is (x, y) and whose size is specified by the width and height arguments.
    The resulting arc covers an area width + 1 pixels wide by height + 1 pixels tall.
    
    Specified by:
    
    fillArc in interface GraphicContext
    
    Parameters:
    
    x - the x coordinate of the upper-left corner of the arc to be drawn.
    
    y - the y coordinate of the upper-left corner of the arc to be drawn.
    
    width - the width of the arc to be drawn.
    
    height - the height of the arc to be drawn.
    
    startAngle - the beginning angle.
    
    arcAngle - the angular extent of the arc, relative to the start angle.
  - getDelegate
```
public Graphics2D getDelegate()
```
    Returns the Graphics2D.
    
    Returns:
    
    the Graphics2D to draw on; never null
  - delegate
```
public Graphics2DGraphicContext delegate(Graphics2D newDelegate)
```
    Sets the Graphics2D.
    
    Parameters:
    
    newDelegate - the Graphics2D to draw on; cannot be null
    
    Returns:
    
    this instance
  - setDelegate
```
public void setDelegate(Graphics2D delegate)
```
    Sets the Graphics2D.
