done

public final void done()

Description copied from interface: ListenableFuture

Terminate and if there is no exception, mark this Future as done and release the internal lock.

Specified by:

done in interface ListenableFuture<V>

abort

public final void abort(java.lang.Throwable t)

Description copied from interface: ListenableFuture

Abort the current processing, and propagate the Throwable to the AsyncHandler or Future

Specified by:

Parameters:

t - the exception

touch

public void touch()

Description copied from interface: ListenableFuture

Touch the current instance to prevent external service to times out.

Specified by:

addListener

public ListenableFuture<V> addListener(java.lang.Runnable listener,
                                       java.util.concurrent.Executor exec)

Description copied from interface: ListenableFuture

Adds a listener and executor to the ListenableFuture. The listener will be passed to the executor for execution when the Future's computation is complete.
Executor can be null, in that case executor will be executed in the thread where completion happens.
There is no guaranteed ordering of execution of listeners, they may get called in the order they were added and they may get called out of order, but any listener added through this method is guaranteed to be called once the computation is complete.

Specified by:

addListener in interface ListenableFuture<V>

Parameters:

listener - the listener to run when the computation is complete.

exec - the executor to run the listener in.

Returns:

this Future
