beginRequest

public void beginRequest(java.util.HashMap map)

Description copied from class: DCDataControl

Invoked in some contexts to signal the beginning of a model request. For example, if the DataControl is referenced in a web application then this method will be invoked by the ADF framework before control is forwarded to the first Servlet defined by the request.

Subclassing datacontrols may extend this method to perform request level initialization of the DataControl.

This method is guaranteed to be called only once per browser request. Page forwards should not result in multiple invocations.

Specified by:

beginRequest in interface ManagedDataControl

Overrides:

beginRequest in class DCDataControl

Parameters:

map - a HashMap representing request context. Web applications which require request context may use the BindingContext.HTTP_REQUEST and BindingContext.HTTP_RESPONSE keys to acquire a reference from from the BindingContext.

endRequest

public void endRequest(java.util.HashMap map)

Description copied from class: DCDataControl

Invoked in some contexts to signal the end of a model request. For example, if the DataControl is referenced in a web application then this method will be invoked by the ADF framework after control is returned from the last Servlet defined by the request page flow.

Subclassing datacontrols may extend this method to perform request level cleanup of the DataControl.

This method is guaranteed to be called only once per browser request. Page forwards should not result in multiple invocations.

Specified by:

endRequest in interface ManagedDataControl

Overrides:

endRequest in class DCDataControl

Parameters:

map - a HashMap representing request context. Web applications which require request context may use the BindingContext.HTTP_REQUEST and BindingContext.HTTP_RESPONSE keys to acquire a reference from from the BindingContext.

resetState

public boolean resetState()

Description copied from class: DCDataControl

Resets the DataControl. DataControl providers should extend this method to reset any model session state that may have been managed by this DataControl. For example:

The ADF/BC DataControl has extended resetState to release the DataControl ApplicationModule to the ApplicationPool in unmanaged release mode.

An EJB DataControl provider may extend resetState to close the DataControl EJB SessionBean

The Toplink DataControl provider extends resetState to reset the DataControl's UnitOfWork and associated RowSetIterators.

Please note that resetState may not occur immediately. If beginRequest has been invoked on the DataControl then resetState processing will be deferred until endRequest processing.

Extending DataControl providers may optionally invoke release(REL_DATA_REFS) after performing and DataControl specific resetState handling.

Specified by:

resetState in interface ManagedDataControl

Overrides:

resetState in class DCDataControl

Returns:

true if resetState was processed immediately. false if resetState was deferred to endRequest processing.
