Method Detail

initialize

public void initialize(AbstractDefinition dcDef)
Initialize the data control to get attributes of data control definition.

Parameters:
context -
node - source node that represents the metadata to connect to the data source

getDefinition

public Definition getDefinition(java.lang.String name,
                                int type)
Description copied from interface: DefinitionProviderDataControl
Returns a definition of the specified type.

Specified by:
getDefinition in interface DefinitionProviderDataControl

invokeOperation

public boolean invokeOperation(java.util.Map map,
                               OperationBinding action)
Invoke a method identified by the given action.

Specified by:
invokeOperation in interface DataControl
Parameters:
map - A Map of bindingContexts that provide access to all binding related objects.
action - Operartion on the datacontrol to be invoked.
Returns:
true if this datacontrol has handled this action, false if the action should be interpreted in the bindings framework or in the caller

getName

public java.lang.String getName()
returns the name of the data control.

Specified by:
getName in interface DataControl

release

public void release()
releases all references to the objects in the data provider layer

Specified by:
release in interface DataControl

getDataProvider

public java.lang.Object getDataProvider()
Return the Business Service Object that this datacontrol is associated with.

Specified by:
getDataProvider in interface DataControl
Returns:
The underlying business service object.

setAttributeValue

public boolean setAttributeValue(AttributeContext ctx,
                                 java.lang.Object value)
Description copied from interface: UpdateableDataControl
This method is called by the data binding framework when a new value is to be set on an attribute in a bean. The attribute and bean are provided in the attribute context along with other framework context information.

Return true if the base framework should skip any further processing of this attribute set. Otherwise return false so that framework can perform a set or put of the attribute value based on introspection.

Specified by:
setAttributeValue in interface UpdateableDataControl

createRowData

public java.lang.Object createRowData(RowContext ctx)
Description copied from interface: UpdateableDataControl
This method is called by the data binding framework when a new row is needed from the data control.

Specified by:
createRowData in interface UpdateableDataControl
Parameters:
ctx - Context of the new row.
Returns:
A data object for the new row.

registerDataProvider

public java.lang.Object registerDataProvider(RowContext ctx)
Description copied from interface: UpdateableDataControl

Specified by:
registerDataProvider in interface UpdateableDataControl
Parameters:
ctx - Context of the row to be modified or removed.
Returns:
The data object that the row represents.

removeRowData

public boolean removeRowData(RowContext ctx)
Description copied from interface: UpdateableDataControl
This method is called by the data binding facility when a row should be removed from the underlying data source.

Specified by:
removeRowData in interface UpdateableDataControl
Parameters:
ctx - Context of the row to be removed.
Returns:
true if the operation is sucessful, false otherwise.

validate

public void validate()
Description copied from interface: UpdateableDataControl
