public class AdapterDCService

extends DCGenericDataControl

Provides services to the adapter created data controls for handling collection and bean based data.

This class is created by the DataControlFactoryImpl to create a service for the data controls that the ADF stacks uses. Created: Thu Nov 04 12:07:04 2004

Method Detail

fetchProviderProperty

protected java.lang.Object fetchProviderProperty(java.lang.String propName)

Fetches the data from the data control.

Overrides:

fetchProviderProperty in class DCGenericDataControl

invokeOperation

public boolean invokeOperation(java.util.Map bindingContext,
                               OperationBinding action)

Invokes the action associated with this data control. The WebService data control invokes the operation to return the data collection assoicated with the operation invocation.

Specified by:

invokeOperation in interface DataControl

Overrides:

invokeOperation in class DCGenericDataControl

Parameters:

bindingContext - A binding context that provide access to all binding related objects.

action - The action to be performed by the data control. For the Webservice data control, the action to be invoked is the webservice operation.

Returns:

true if this datacontrol has handled this action, false if the action should be interpreted in the bindings framework or in the caller.

hasOperationParamsChanged

public boolean hasOperationParamsChanged(OperationInfo operationInfo)

Check if the operation params has changed during an iterator execution. This method decides whether to call a method. If the parameter values are changed the method will be called again to get the result for the changed value. Otherwise it'll call the AbstractImpl (if implemented) to decide whether to call the method again.

Overrides:

hasOperationParamsChanged in class DCDataControl

Parameters:

operationInfo - The OperationInfo whose parameters need to evaluated to decide this params changed condition.

Returns:

true if the operation parameters have changed. Otherwise calls the impl to decide. If the impl is not available, i.e. the data control is not an AbstractImpl, it returns false.

applySortCriteria

protected void applySortCriteria(DCIteratorBinding iter,
                                 oracle.jbo.SortCriteria[] sortby)

Sets the sort critiera that will be applied next time when the source for this iteratorBinding is executed.

Overrides:

applySortCriteria in class DCGenericDataControl
