public class StandardRenderPolicy
extends OMComponent
implements RenderPolicy

The StandardRenderPolicy is a RenderPolicy that simply paints the current graphic list. No conditions or deviations are considered.

Don't pass in a null layer.

Method Summary

java.awt.Composite	getComposite()
OMGraphicHandlerLayer	getLayer() A method to get the parent layer on the RenderPolicy.
void	paint(java.awt.Graphics g) Assumes that the OMGraphicList to be rendered is set on the OMGraphicHandlerLayer, available via setList().
OMGraphicList	prepare() Called when an OMGraphicHandlerLayer should begin preparing OMGraphics for the map.
void	prePrepare(Projection newProj) The StandardRenderPolicy doesn't need to do anything before prepare() returns.
void	setComposite(java.awt.Composite composite) Can be used to set Composite objects (like AlphaComposite) on Graphics2D objects before the layer is painted.
protected void	setCompositeOnGraphics(java.awt.Graphics2D g) Call made by the policy from the paint(g) method in order to set the composite on the Graphics2D object.
void	setLayer(OMGraphicHandlerLayer l) A method to set the parent layer on the RenderPolicy.

Method Detail

setLayer

public void setLayer(OMGraphicHandlerLayer l)

Description copied from interface: RenderPolicy

A method to set the parent layer on the RenderPolicy.

Specified by:

setLayer in interface RenderPolicy

getLayer

public OMGraphicHandlerLayer getLayer()

Description copied from interface: RenderPolicy

A method to get the parent layer on the RenderPolicy.

Specified by:

getLayer in interface RenderPolicy

getComposite

public java.awt.Composite getComposite()

Specified by:

getComposite in interface RenderPolicy

setComposite

public void setComposite(java.awt.Composite composite)

Can be used to set Composite objects (like AlphaComposite) on Graphics2D objects before the layer is painted.

Specified by:

setComposite in interface RenderPolicy

Parameters:

composite -

setCompositeOnGraphics

protected void setCompositeOnGraphics(java.awt.Graphics2D g)

Call made by the policy from the paint(g) method in order to set the composite on the Graphics2D object. This method is meant to be overridden if needed.

Parameters:

g - Graphics2D that the Composite will be set on.

prePrepare

public void prePrepare(Projection newProj)

The StandardRenderPolicy doesn't need to do anything before prepare() returns.

Specified by:

prePrepare in interface RenderPolicy

Parameters:

newProj - the new projection received in a projectionChanged method for the layer.

prepare

public OMGraphicList prepare()

Description copied from interface: RenderPolicy

Called when an OMGraphicHandlerLayer should begin preparing OMGraphics for the map. This is a hook into the list to help RenderPolicy make decisions or set up the list for faster rendering.

Specified by:

prepare in interface RenderPolicy

paint

public void paint(java.awt.Graphics g)

Assumes that the OMGraphicList to be rendered is set on the OMGraphicHandlerLayer, available via setList().

Specified by:

paint in interface RenderPolicy
