Method Summary

void	cleanup(RenderingContext context) RenderingContext implementations must call cleanup() once after the last callto getDataObject().
DataObject	getDataObject(RenderingContext context, java.lang.String namespace, java.lang.String name)
void	init(RenderingContext context) RenderingContext implementations must call init() once before calling getDataObject().

Method Detail

getDataObject

public DataObject getDataObject(RenderingContext context,
                                java.lang.String namespace,
                                java.lang.String name)

Parameters:

context - the current rendering context

namespace - the namespace of the requested DataObject

name - the name of the requested DataObject

Returns:

the DataObject for the specified namespace and name, or null if no such dataObject exists.

init

public void init(RenderingContext context)

RenderingContext implementations must call init() once before calling getDataObject(). In general, they should try to call it as early as possible.

cleanup

public void cleanup(RenderingContext context)

RenderingContext implementations must call cleanup() once after the last callto getDataObject().
