* the object resulting from the future is not defined and implementations may use it to convey
* additional information related to the publishing process.
- *
* Abstract subclasses can refine the return type as returning a promise of a more specific

- *
* public interface DeliveryStatus { int getListenerCount(); } ListenableFuture<? extends
* DeliveryStatus>[ putNotification(DOMNotification notification);

* Once the Future succeeds, the resulting object can be queried for traits using instanceof,
* e.g:
- *
* // Can block when (for example) the implemention's ThreadPool queue is full Object o =
* service.putNotification(notif).get(); if (o instanceof DeliveryStatus) { DeliveryStatus ds =
* (DeliveryStatus)o; LOG.debug("Notification was received by {} listeners",
* ds.getListenerCount();); } }
- *
* In case an implementation is running out of resources, it can block the calling thread until
* enough resources become available to accept the notification for processing, or it is
* interrupted.
*
+ * <p>
* Caution: completion here means that the implementation has completed processing of the
* notification. This does not mean that all existing registrants have seen the notification.
* Most importantly, the delivery process at other cluster nodes may have not begun yet.
* @throws InterruptedException if interrupted while waiting
* @throws NullPointerException if notification is null.
