Class SettableFuture<T>

java.lang.Object
  com.atlassian.util.concurrent.SettableFuture<T>

All Implemented Interfaces:

java.util.concurrent.Future<T>

@ThreadSafe
public class SettableFuture<T>
extends java.lang.Object
implements java.util.concurrent.Future<T>

SettableFuture is a Future implementation where the responsibility for producing the result is external to the future instance, unlike FutureTask where the future holds the operation (a Callable or Runnable instance) and the first thread that calls FutureTask.run() executes the operation.

This is useful in situations where all the inputs may not be available at construction time.

This class does not support cancellation.
