The appropriate DataProvider is selected by indexing using the namespace and the name.

Constructor Summary

TableDataProvider()

Method Summary

void	cleanup(RenderingContext context) RenderingContext implementations must call cleanup() once after the last call to getDataObject().
DataObject	getDataObject(RenderingContext context, java.lang.String namespace, java.lang.String name) delegates to an associated DataProvider by namespace and name.
void	init(RenderingContext context) RenderingContext implementations must call init() once before calling getDataObject().
void	put(java.lang.String namespace, DataProvider provider) Associates a DataProvider with an entire namespace.
void	put(java.lang.String namespace, java.lang.String name, DataObject dataObject) Associates a DataObject with a namespace and a name

Method Detail

put

public final void put(java.lang.String namespace,
                      java.lang.String name,
                      DataObject dataObject)

Associates a DataObject with a namespace and a name

put

public void put(java.lang.String namespace,
                java.lang.String name,
                DataProvider provider)

Associates a DataProvider with a namespace and a name

put

public void put(java.lang.String namespace,
                DataProvider provider)

Associates a DataProvider with an entire namespace. Providers registered against a namespace have lower priority than any provider registered against a specific name within that namespace.

getDataObject

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

delegates to an associated DataProvider by namespace and name.
