Method Detail

clearCaches

public void clearCaches()

This methods needs to get called after the container got started. This is to avoid that events which already got fired during bootstrap in Extensions will get cached and events from beans thus get ignored.

hasContextLifecycleObserver

public boolean hasContextLifecycleObserver(Annotation lifecycleEvent)

Parameters:

lifecycleEvent - e.g. DestroyedLiteral.INSTANCE_REQUEST_SCOPED

Returns:

whether the given Initialized or Destroyed event has observer methods.

getObserverMethods

public List<javax.enterprise.inject.spi.ObserverMethod<?>> getObserverMethods()

addObserver

public <T> void addObserver(javax.enterprise.inject.spi.ObserverMethod<T> observer)

resolveObservers

public <T> Collection<javax.enterprise.inject.spi.ObserverMethod<? super T>> resolveObservers(T event,
                                                                                              EventMetadataImpl metadata,
                                                                                              boolean isLifecycleEvent)

getDefaultNotificationOptions

public javax.enterprise.event.NotificationOptions getDefaultNotificationOptions()

fireEvent

public <T> CompletionStage<T> fireEvent(Object event,
                                        EventMetadataImpl metadata,
                                        boolean isLifecycleEvent,
                                        javax.enterprise.event.NotificationOptions notificationOptions)
