public class SimpleNotifyEventListenerContainer
extends AbstractNotifyEventListenerContainer

A simple notification based container allowing to register a SpaceDataEventListener that will be triggered by notifications. Uses AbstractNotifyEventListenerContainer for configuration of different notification registration parameters and transactional semantics.

Allows to control using setRegisterOnStartup(boolean) if the listener will be registered for notification on startup or registration will be controlled by the AbstractEventListenerContainer.doStart() and AbstractSpaceListeningContainer.doStop() callbacks (which by default are triggered based on the current space mode - PRIMARY or BACKUP). Default is false which means registration will occur when the space moves into PRIMARY mode (assuming that AbstractSpaceListeningContainer.setActiveWhenPrimary(boolean) is set to true, which is the default).

The container can automatically take the notified event data (using GigaSpace.take(Object)) if the setPerformTakeOnNotify(boolean) is set to true. Defaults to false. If the flag is set to true, setIgnoreEventOnNullTake(boolean) can control of the event will be propagated to the event listener if the take operation returned null.

public SimpleNotifyEventListenerContainer()

Method Detail

setRegisterOnStartup

public void setRegisterOnStartup(boolean registerOnStartup)

setPerformTakeOnNotify

public void setPerformTakeOnNotify(boolean performTakeOnNotify)

If set to true will remove the event from the space using take operation. Default is false.

setIgnoreEventOnNullTake

public void setIgnoreEventOnNullTake(boolean ignoreEventOnNullTake)

If set to true, will not propagate the event if the take operation returned null. This flag only makes sense when setPerformTakeOnNotify(boolean) is set to true. Defaults to false.

doInitialize

protected void doInitialize()
                     throws DataAccessException

Description copied from class: AbstractSpaceListeningContainer

Register any invokers within this container.

Subclasses need to implement this method for their specific invoker management process.

Specified by:

doInitialize in class AbstractSpaceListeningContainer

Throws:

DataAccessException

doShutdown

protected void doShutdown()
                   throws DataAccessException

Description copied from class: AbstractSpaceListeningContainer
