Class DistributedTask<V>

java.lang.Object
  java.util.concurrent.FutureTask<V>
      com.hazelcast.core.DistributedTask<V>

All Implemented Interfaces:

Runnable, Future<V>, RunnableFuture<V>

Direct Known Subclasses:

MultiTask

public class DistributedTask<V>
extends FutureTask<V>

A cancellable asynchronous distributed computation.

This class is analogue to java.util.concurrent.FutureTask.

Once the computation has completed, the computation cannot be restarted or cancelled.
