Javadoc

Interface for polling a Callable instance provided by the user. Use when you need to put something in the background (e.g. a remote invocation) and wait for the result, e.g.

 
Poller<Result> poller = ... 
final long id = remoteService.execute(); // do something remotely 
Future<Result> future = poller.poll(new Callable<Result> { 
public Object call() { 
// Look for the result (null if not ready) 
return remoteService.get(id); 
} 
}); 
Result result = future.get(1000L, TimeUnit.MILLISECONDS);
