Direct Known Subclasses:
ImmediateFuture.ImmediateCancelledFuture, ImmediateFuture.ImmediateFailedFuture, SettableFuture
Enclosing class:
AbstractFuture<V>
abstract static class AbstractFuture.TrustedFuture<V> extends AbstractFuture<V> implements AbstractFuture.Trusted<V>
A less abstract subclass of AbstractFuture. This can be used to optimize setFuture by ensuring that get() calls exactly the implementation of AbstractFuture.get(long, java.util.concurrent.TimeUnit).

    • get

      @CanIgnoreReturnValue public final V get() throws InterruptedException, ExecutionException
      Description copied from class: AbstractFuture

      The default AbstractFuture implementation throws InterruptedException if the current thread is interrupted during the call, even if the value is already available.

      Specified by:
      get in interface Future<V>
      Overrides:
      get in class AbstractFuture<V>
      Throws:
      InterruptedException
      ExecutionException

    • get

      @CanIgnoreReturnValue public final V get(long timeout, TimeUnit unit) throws InterruptedException, ExecutionException, TimeoutException
      Description copied from class: AbstractFuture

      The default AbstractFuture implementation throws InterruptedException if the current thread is interrupted during the call, even if the value is already available.

      Specified by:
      get in interface Future<V>
      Overrides:
      get in class AbstractFuture<V>
      Throws:
      InterruptedException
      ExecutionException
      TimeoutException

    • isDone

      public final boolean isDone()
      Specified by:
      isDone in interface Future<V>
      Overrides:
      isDone in class AbstractFuture<V>

    • isCancelled

      public final boolean isCancelled()
      Specified by:
      isCancelled in interface Future<V>
      Overrides:
      isCancelled in class AbstractFuture<V>

    • addListener

      public final void addListener(Runnable listener, Executor executor)
      Description copied from class: AbstractFuture
      Registers a listener to be run on the given executor. The listener will run when the Future's computation is complete or, if the computation is already complete, immediately.

      There is no guaranteed ordering of execution of listeners, but any listener added through this method is guaranteed to be called once the computation is complete.

      Exceptions thrown by a listener will be propagated up to the executor. Any exception thrown during Executor.execute (e.g., a RejectedExecutionException or an exception thrown by direct execution) will be caught and logged.

      Note: For fast, lightweight listeners that would be safe to execute in any thread, consider MoreExecutors.directExecutor(). Otherwise, avoid it. Heavyweight directExecutor listeners can cause problems, and these problems can be difficult to reproduce because they depend on timing. For example:

      • The listener may be executed by the caller of addListener. That caller may be a UI thread or other latency-sensitive thread. This can harm UI responsiveness.
      • The listener may be executed by the thread that completes this Future. That thread may be an internal system thread such as an RPC network thread. Blocking that thread may stall progress of the whole system. It may even cause a deadlock.
      • The listener may delay other listeners, even listeners that are not themselves directExecutor listeners.

      This is the most general listener interface. For common operations performed using listeners, see Futures. For a simplified but general listener interface, see addCallback().

      Memory consistency effects: Actions in a thread prior to adding a listener happen-before its execution begins, perhaps in another thread.

      Guava implementations of ListenableFuture promptly release references to listeners after executing them.

      Specified by:
      addListener in interface ListenableFuture<V>
      Overrides:
      addListener in class AbstractFuture<V>
      Parameters:
      listener - the listener to run when the computation is complete
      executor - the executor to run the listener in

    • cancel

      @CanIgnoreReturnValue public final boolean cancel(boolean mayInterruptIfRunning)
      Description copied from class: AbstractFuture

      If a cancellation attempt succeeds on a Future that had previously been set asynchronously, then the cancellation will also be propagated to the delegate Future that was supplied in the setFuture call.

      Rather than override this method to perform additional cancellation work or cleanup, subclasses should override AbstractFuture.afterDone(), consulting AbstractFuture.isCancelled() and AbstractFuture.wasInterrupted() as necessary. This ensures that the work is done even if the future is cancelled without a call to cancel, such as by calling setFuture(cancelledFuture).

      Specified by:
      cancel in interface Future<V>
      Overrides:
      cancel in class AbstractFuture<V>
