Method Details

done

void done()

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

Parameters:

callable -

abort

void abort(Throwable t)

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

Parameters:

t -

touch

void touch()

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

addListener

ListenableFuture<V> addListener(Runnable listener,
 Executor exec)

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.

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.

Parameters:

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

exec - the executor to run the listener in.

Returns:

this Future

Throws:

NullPointerException - if the executor or listener was null.

RejectedExecutionException - if we tried to execute the listener immediately but the executor rejected it.
