14.4. 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.
14.4.1. NotifyingFutures Example
The following is an example depicting how to use
NotifyingFutures in Red Hat JBoss Data Grid:
FutureListener futureListener = new FutureListener() {
public void futureDone(Future future) {
try {
future.get();
} catch (Exception e) {
// Future did not complete successfully
System.out.println("Help!");
}
}
};
cache.putAsync("key", "value").attachListener(futureListener);
