Class Future

java.lang.Object
  org.kth.dks.util.Future

Direct Known Subclasses:

ReusableFuture

public class Future
extends java.lang.Object

Future implements a facility to wait for the result of an asynchronous computation. It is meant to be an implementation of the java.util.concurrent.Future interface, although to be compilable with JSE 1.4, generics are not used. If you have 5.0, probably use java.util.concurrent.FutureTask instead. The future class decouples the underlying computations from the return mechanism. That is, the cancel method will never actually cancel any computation that computes the value of the future. The class supports multiple waiters.
