• Constructor Detail

  • DefaultChannelPromise

    public DefaultChannelPromise(Channel channel)

    Creates a new instance.

    Parameters:

    channel - the Channel associated with this future

  • DefaultChannelPromise

    public DefaultChannelPromise(Channel channel,
     EventExecutor executor)

    Creates a new instance.

    Parameters:

    channel - the Channel associated with this future

• Method Detail

  • executor

    protected EventExecutor executor()

    Description copied from class: DefaultPromise
    Get the executor used to notify listeners when this promise is complete.

    It is assumed this executor will protect against StackOverflowError exceptions. The executor may be used to avoid StackOverflowError by executing a Runnable if the stack depth exceeds a threshold.

    Overrides:

    executor in class DefaultPromise<java.lang.Void>

    Returns:

    The executor used to notify listeners when this promise is complete.

  • channel

    public Channel channel()

  • setSuccess

    public ChannelPromise setSuccess()

    Specified by:

    setSuccess in interface ChannelPromise

  • setSuccess

    public ChannelPromise setSuccess(java.lang.Void result)

    Description copied from interface: Promise
    Marks this future as a success and notifies all listeners. If it is success or failed already it will throw an IllegalStateException.

    Specified by:

    trySuccess in interface ChannelPromise

  • setFailure

    public ChannelPromise setFailure(java.lang.Throwable cause)

    Description copied from interface: Promise
    Marks this future as a failure and notifies all listeners. If it is success or failed already it will throw an IllegalStateException.

    Specified by:

    Specified by:

    setFailure in interface Promise<java.lang.Void>

    Overrides:

    setFailure in class DefaultPromise<java.lang.Void>

  • addListener

    public ChannelPromise addListener(GenericFutureListener<? extends Future<? super java.lang.Void>> 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:
