broadcastNow in interface EventIpcBroadcaster

addEventListener

public void addEventListener(EventListener listener)

Register an event listener that is interested in all events. Removes this listener from any UEI-specific matches.

Specified by:

addEventListener in interface EventSubscriptionService

addEventListener

public void addEventListener(EventListener listener,
                             Collection<String> ueis)

addEventListener

public void addEventListener(EventListener listener,
                             String uei)

Register an event listener interested in the passed UEI.

Specified by:

addEventListener in interface EventSubscriptionService

removeEventListener

public void removeEventListener(EventListener listener,
                                Collection<String> ueis)

Removes a registered event listener. The UEI list indicates the list of events the listener is no more interested in. Note: The listener thread for this listener is not stopped until the 'removeEventListener(EventListener listener)' method is called.

Specified by:

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

getEventHandler

public EventHandler getEventHandler()

setEventHandler

public void setEventHandler(EventHandler eventHandler)

getHandlerPoolSize

public int getHandlerPoolSize()

setHandlerPoolSize
