16 * An aggregated listener registration. This is a result of registering an invoker which can handle multiple
17 * interfaces at the same time. In order to support correct delivery, we need to maintain per-type registrations
18 * which get squashed if a notification which implements multiple interfaces is encountered.
21 * We take care of that by implementing alternate {@link #hashCode()}/{@link #equals(Object)}, which resolve
22 * to the backing aggregator.
