ManagedExecutorCompletionService

public ManagedExecutorCompletionService(AbstractManagedExecutorService executor,
                                BlockingQueue<Future<V>> completionQueue)

Creates an ExecutorCompletionService using the supplied executor for base task execution and the supplied queue as its completion queue.
