Method Detail

setProgress

public ProgressivePromise<V> setProgress(long progress,
                                         long total)

Description copied from interface: ProgressivePromise

Sets the current progress of the operation and notifies the listeners that implement ProgressiveFutureListener.

Specified by:

setProgress in interface ProgressivePromise<V>

tryProgress

public boolean tryProgress(long progress,
                           long total)

Description copied from interface: ProgressivePromise

Tries to set the current progress of the operation and notifies the listeners that implement ProgressiveFutureListener. If the operation is already complete or the progress is out of range, this method does nothing but returning false.

Specified by:

tryProgress in interface ProgressivePromise<V>

setSuccess

public ProgressivePromise<V> setSuccess(V 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:

setSuccess in interface ProgressivePromise<V>

Specified by:

setSuccess in interface Promise<V>

Overrides:

setSuccess in class DefaultPromise<V>

setFailure

public ProgressivePromise<V> setFailure(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:

setFailure in interface ProgressivePromise<V>

Specified by:

setFailure in interface Promise<V>

Overrides:

setFailure in class DefaultPromise<V>

addListener

public ProgressivePromise<V> addListener(FutureListener<? 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>

Specified by:

addListener in interface ProgressiveFuture<V>

Specified by:

addListener in interface ProgressivePromise<V>

Specified by:

addListener in interface Promise<V>

Overrides:

addListener in class DefaultPromise<V>

removeListener

public ProgressivePromise<V> removeListener(FutureListener<? 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>

Specified by:

removeListener in interface ProgressiveFuture<V>

Specified by:

removeListener in interface ProgressivePromise<V>

Specified by:

removeListener in interface Promise<V>

Overrides:

removeListener in class DefaultPromise<V>

sync

public ProgressivePromise<V> sync()
                           throws 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>

Specified by:

sync in interface ProgressiveFuture<V>

Specified by:

sync in interface ProgressivePromise<V>

Specified by:

Overrides:

sync in class DefaultPromise<V>

Throws:

InterruptedException

await

public ProgressivePromise<V> await()
                            throws InterruptedException

Description copied from interface: Future
