Style renderer that renders JavaImageNodeStyle instances.

Note that this style renderer doesn't invoke paint or paintNode. Subclasses have to override the createDisplayObject and updateDisplayObject methods.

Method Detail
createDisplayObject()method
override public function createDisplayObject(context:IDisplayObjectContext):DisplayObject

Creates a new DisplayObject from scratch.

Parameters

context:IDisplayObjectContext — The context for which the display object is created.

Returns
DisplayObject — A DisplayObject.
lookup()method 
override public function lookup(type:Class):Object

Implements the ILookup interface.

This method will be used by default if getContext has been queried for a lookup implementation. Note that it cannot be assumed that configure has already been invoked. However, normally item and style will be correctly configured if invoked directly after getContext. Subclass implementations should make sure to configure this instance before they return this as a result of a successful lookup.

Parameters

type:Class — The type to query for

Returns
Object — An implementation of the given type or null
updateDisplayObject()method 
override public function updateDisplayObject(oldDisplayObject:DisplayObject, context:IDisplayObjectContext):DisplayObject

Updates the given DisplayObject or creates a new one.

Implementors can decide whether they update the given display object or create a new one. Updating can mean re-rendering or updating size and/or coordinates.

Parameters

oldDisplayObject:DisplayObject — The display object to update.
 
context:IDisplayObjectContext — The context for which the display object should be updated.

Returns
DisplayObject — The updated display object or a completely new display object.
