Method Detail

prepareUpdate

public void prepareUpdate(BeanUpdateEvent event)
                   throws BeanUpdateRejectedException

Description copied from interface: BeanUpdateListener

Called when a proposed update includes an update to the source bean. The implementation should examine the proposed update and either accept it (by returning) or reject it (by throwing a BeanUpdateRejectedException). If the listener rejects the update, the entire descriptor update will be aborted.

Specified by:

prepareUpdate in interface BeanUpdateListener

Parameters:

event - - description of proposed update to bean

Throws:

BeanUpdateRejectedException - to reject the update.

activateUpdate

public void activateUpdate(BeanUpdateEvent event)
                    throws BeanUpdateFailedException

Description copied from interface: BeanUpdateListener

Called when a descriptor update that includes an update to the source bean is activated.

Specified by:

activateUpdate in interface BeanUpdateListener

Parameters:

event - - a description of the changes to the target bean

Throws:

BeanUpdateFailedException - to indicate that failures occurred while activating the update.

rollbackUpdate

public void rollbackUpdate(BeanUpdateEvent event)

Description copied from interface: BeanUpdateListener

Called when a descriptor update has been abandoned that included an proposed update to the source bean. Note that this method may not fail. If a failure occurs during rollback, its effect should be logged and isolated by the listener.

Specified by:

rollbackUpdate in interface BeanUpdateListener

Parameters:

event - - a description of the changes to the target bean that are being abandoned.
