12.4. NotifyingFutures
Methods in Red Hat JBoss Data Grid do not return Java Development Kit (JDK)
Futures, but a sub-interface known as a NotifyingFuture. Unlike a JDK Future, a listener can be attached to a NotifyingFuture to notify the user about a completed future.
Note
NotifyingFutures are only available in JBoss Data Grid Library mode.

public void futureDone(Future future) {
try {

} catch (Exception e) {
// Future did not complete successfully
System.out.println("Help!");
}
}
};
cache.putAsync("key", "value").attachListener(futureListener);
