Class SampleDataProvider

java.lang.Object
  |
  +--oracle.cabo.ui.debug.SampleDataProvider

All Implemented Interfaces:

DataProvider

public class SampleDataProvider

extends java.lang.Object

implements DataProvider

DataProvider that guesses at sample data. In order for this provider to do its job, special "hints" need to be attached to BoundValues. The XML parser supports this automatically, so this feature is likely only useable within UIX.

Constructor Summary

SampleDataProvider()

Method Summary

void	cleanup(RenderingContext context) RenderingContext implementations must call cleanup() once after the last callto getDataObject().
static BoundValue	createBoundValue(BoundValue base, AttributeKey attributeKey) Creates a BoundValue that will supply the needed hint.
static void	enableHintParsing(ParseContext context) Activates hints for data parsing.
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().
static boolean	isHintParsingEnabled(ParseContext context) Tests if hints should be added.
static DataProvider	sharedInstance() Returns the shared instance of this provider.

public SampleDataProvider()

Method Detail

sharedInstance

public static DataProvider sharedInstance()

Returns the shared instance of this provider.

enableHintParsing

public static void enableHintParsing(ParseContext context)

Activates hints for data parsing.

isHintParsingEnabled

public static boolean isHintParsingEnabled(ParseContext context)

Tests if hints should be added.

createBoundValue

public static BoundValue createBoundValue(BoundValue base,
                                          AttributeKey attributeKey)

Creates a BoundValue that will supply the needed hint.

getDataObject

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

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().

Specified by:

cleanup in interface DataProvider
