Copy it again:
I use it like following lines:
TopicsContext topicsContext = TopicsContext.lookup();
Topic topic = topicsContext.getOrCreateTopic(new TopicKey("test"));
topic.setMessageDataSerializer(DefaultMessageDataSerializer.instance());
topic.addTopicListener(new SessionTopicListener2() {
@Override
public void processPreSubscriptionEvent(SessionPreSubscriptionEvent
event) throws SubscriptionFailureException {
//TODO
}
@Override
public void processSubscriptionEvent(SessionSubscriptionEvent
event) {
//TODO
}
@Override
public void processUnsubscriptionEvent(SessionUnsubscriptionEvent
event) {
//TODO
}
});
I noted that listeners in TopicImpl are all the SessionTopicListener2 type,
because add method is:
public void addTopicListener(TopicListener topicListener) {
TopicListener listener = topicListener;
if (listener instanceof SessionTopicListener) {
listener = new SessionTopicListenerWrapper((SessionTopicListener)
listener);
}
listeners.add(listener);
}
All SessionTopicListeners are wrapped to type SessionTopicListener2, and when
event publish in TopicImpl, it check it if it is appropriate listener like this:
public void publishEvent(TopicEvent event) {
for (TopicListener listener : listeners) {
if (event.isAppropriateListener(listener)) {
try {
event.invokeListener(listener);
} catch (Exception e) {
logError(e);
}
}
}
}
But event type SessionPreSubscriptionEvent, SessionSubscriptionEvent or
SessionUnsubscriptionEvent does not override the mothed isAppropriateListener,
so when checking, it use the method of its parent SessionTopicEvent, its parent
method is like this:
@Override
public boolean isAppropriateListener(EventListener listener) {
return (listener instanceof SessionTopicListener);
}
Then it always returns false for above three SessionTopicEvent , and the custom
listeners will never be called. I think it may be changed from " return
(listener instanceof SessionTopicListener);" to return (listener instanceof
SessionTopicListener2); or override it in seperator implement of type
SessionTopicEvent .
