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.

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:

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

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

This method is called by the data binding facility before the row in the RowContext object is modified or marked as removed, so the row can be marked dirty by the data control.

Specified by:

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
