public final void setPoints(Location[] la)

Sets the co-ordinates for each point that defines the polygon.

getPoints

public final Location[] getPoints()

Returns:

Returns the co-ordinates for each point in the polygon

getBackground

public Fill getBackground()

Overrides:

getBackground in class PrimitiveRenderEvent

Returns:

Returns the background fill attributes for the polygon

setBackground

public void setBackground(Fill ifBackground)

Sets the background fill attributes for the polygon

getOutline

public LineAttributes getOutline()

Returns:

Returns the polygon outline attributes.

setOutline

public void setOutline(LineAttributes lia)

Sets the polygon outline attributes

getBounds

public Bounds getBounds()
                 throws ChartException

Description copied from class: PrimitiveRenderEvent

Returns the mimimum bounds required to contain the rendering area for current event.

Overrides:

getBounds in class PrimitiveRenderEvent

Returns:

Throws:

ChartException - if not implemented by concrete class

copy

public PrimitiveRenderEvent copy()

Overrides:

copy in class PrimitiveRenderEvent

Returns:

A copy of this primitive rendering instruction implemented by subclasses

draw

public final void draw(IDeviceRenderer idr)
                throws ChartException

Description copied from class: PrimitiveRenderEvent

Causes this instruction to 'draw' itself on the device renderer

Overrides:

Overrides:

fill in class PrimitiveRenderEvent

Throws:

ChartException

reset

public void reset()

Description copied from class: ChartEvent
