Constructor Summary

BeanDataProvider(BoundValue value, boolean useLocalName)
Creates a BeanDataProvider

Method Summary

void	cleanup(RenderingContext context) RenderingContext implementations must call cleanup() once after the last callto getDataObject().
DataObject	getDataObject(RenderingContext context, java.lang.String namespaceURI, java.lang.String localName)

Constructor Detail

BeanDataProvider

public BeanDataProvider(BoundValue value,
                        boolean useLocalName)

Creates a BeanDataProvider

Parameters:

value - the BoundValue used to retrieve the bean

useLocalName - if true, the object returned from the bound value will be interpreted as a DataObject itself; the "localName" of the data object being requested will be used as a select key. This feature makes it feasible to use a single BeanDataProvider to serve a set of beans.

Method Detail

getDataObject

public DataObject getDataObject(RenderingContext context,
                                java.lang.String namespaceURI,
                                java.lang.String localName)

Specified by:

getDataObject in interface DataProvider

Following copied from interface: oracle.cabo.ui.data.DataProvider

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)

Description copied from interface: DataProvider

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

Specified by:

init in interface DataProvider

cleanup

public void cleanup(RenderingContext context)

Description copied from interface: DataProvider

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