java.util.TooManyListenersException

The TooManyListenersException Exception is used as part of the Java Event model to annotate and implement a unicast special case of a multicast Event Source.

The presence of a "throws TooManyListenersException" clause on any given concrete implementation of the normally multicast "void addXyzEventListener" event listener registration pattern is used to annotate that interface as implementing a unicast Listener special case, that is, that one and only one Listener may be registered on the particular event listener source concurrently.

            throws TooManyListenersException {


        if (sipStack.sipListener == null) {
            sipStack.sipListener = sipListener;
        } else if (sipStack.sipListener != sipListener) {
            throw new TooManyListenersException(
                    "Stack already has a listener. Only one listener per stack allowed");
        }


        if (sipStack.isLoggingEnabled())
            sipStack.getStackLogger().logDebug("add SipListener " + sipListener);
