@Metadata(value="org.glassfish.hk2.messaging.eventReceiverTypes")
public abstract Class<?>[] value

A list of event types that this service may receive. The default value of an empty array represents any event type. Be warned that if the default value is used that any event being fired will cause the descriptor with this qualifier to get reified (classloaded) which may be expensive. In order to have a more efficient application it is better to fill this value in with all the event types this service might receive

Returns:

A list of the classes that might be received as topic events. If the empty set then this class might receive any topic event

Default:

{}
