Interface Promise<V>

    • Method Detail

      • setSuccess

        Promise<V> setSuccess​(V result)
        Marks this future as a success and notifies all listeners. If it is success or failed already it will throw an IllegalStateException.
      • trySuccess

        boolean trySuccess​(V result)
        Marks this future as a success and notifies all listeners.
        Returns:
        true if and only if successfully marked this future as a success. Otherwise false because this future is already marked as either a success or a failure.
      • setFailure

        Promise<V> setFailure​(java.lang.Throwable cause)
        Marks this future as a failure and notifies all listeners. If it is success or failed already it will throw an IllegalStateException.
      • tryFailure

        boolean tryFailure​(java.lang.Throwable cause)
        Marks this future as a failure and notifies all listeners.
        Returns:
        true if and only if successfully marked this future as a failure. Otherwise false because this future is already marked as either a success or a failure.
      • setUncancellable

        boolean setUncancellable()
        Make this future impossible to cancel.
        Returns:
        true if and only if successfully marked this future as uncancellable or it is already done without being cancelled. false if this future has been cancelled already.
      • addListener

        Promise<V> addListener​(GenericFutureListener<? extends Future<? super V>> listener)
        Description copied from interface: Future
        Adds the specified listener to this future. The specified listener is notified when this future is done. If this future is already completed, the specified listener is notified immediately.
        Specified by:
        addListener in interface Future<V>
      • addListeners

        Promise<V> addListeners​(GenericFutureListener<? extends Future<? super V>>... listeners)
        Description copied from interface: Future
        Adds the specified listeners to this future. The specified listeners are notified when this future is done. If this future is already completed, the specified listeners are notified immediately.
        Specified by:
        addListeners in interface Future<V>
      • removeListener

        Promise<V> removeListener​(GenericFutureListener<? extends Future<? super V>> listener)
        Description copied from interface: Future
        Removes the first occurrence of the specified listener from this future. The specified listener is no longer notified when this future is done. If the specified listener is not associated with this future, this method does nothing and returns silently.
        Specified by:
        removeListener in interface Future<V>
      • removeListeners

        Promise<V> removeListeners​(GenericFutureListener<? extends Future<? super V>>... listeners)
        Description copied from interface: Future
        Removes the first occurrence for each of the listeners from this future. The specified listeners are no longer notified when this future is done. If the specified listeners are not associated with this future, this method does nothing and returns silently.
        Specified by:
        removeListeners in interface Future<V>
      • await

        Promise<V> await()
                  throws java.lang.InterruptedException
        Description copied from interface: Future
        Waits for this future to be completed.
        Specified by:
        await in interface Future<V>
        Throws:
        java.lang.InterruptedException - if the current thread was interrupted
      • awaitUninterruptibly

        Promise<V> awaitUninterruptibly()
        Description copied from interface: Future
        Waits for this future to be completed without interruption. This method catches an InterruptedException and discards it silently.
        Specified by:
        awaitUninterruptibly in interface Future<V>
      • sync

        Promise<V> sync()
                 throws java.lang.InterruptedException
        Description copied from interface: Future
        Waits for this future until it is done, and rethrows the cause of the failure if this future failed.
        Specified by:
        sync in interface Future<V>
        Throws:
        java.lang.InterruptedException
      • syncUninterruptibly

        Promise<V> syncUninterruptibly()
        Description copied from interface: Future
        Waits for this future until it is done, and rethrows the cause of the failure if this future failed.
