Method Detail

trySuccess

boolean trySuccess(T result)

Marks this future as a success and notifies all listeners.

Parameters:

result - object

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.

tryFailure

boolean tryFailure(Throwable cause)

Marks this future as a failure and notifies all listeners.

Parameters:

cause - object

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.

await

RPromise<T> await()
           throws InterruptedException

Description copied from interface: RFuture

Waits for this future to be completed.

Specified by:

await in interface RFuture<T>

Returns:

Future object

Throws:

InterruptedException - if the current thread was interrupted

awaitUninterruptibly

RPromise<T> awaitUninterruptibly()

Description copied from interface: RFuture

Waits for this future to be completed without interruption. This method catches an InterruptedException and discards it silently.

Specified by:

awaitUninterruptibly in interface RFuture<T>

Returns:

Future object

sync

RPromise<T> sync()
          throws InterruptedException

Description copied from interface: RFuture

Waits for this future until it is done, and rethrows the cause of the failure if this future failed.

Specified by:

sync in interface RFuture<T>

Returns:

Future object

Throws:

InterruptedException - if the current thread was interrupted

syncUninterruptibly

RPromise<T> syncUninterruptibly()

Description copied from interface: RFuture

Waits for this future until it is done, and rethrows the cause of the failure if this future failed.

Specified by:

syncUninterruptibly in interface RFuture<T>

Returns:

Future object

hasListeners

boolean hasListeners()
