final class TimeoutFuture<V> extends FluentFuture.TrustedFuture<V>
Futures#withTimeout
.
Future that delegates to another but will finish early (via a TimeoutException
wrapped
in an ExecutionException
) if the specified duration expires. The delegate future is
interrupted and cancelled if it times out.

AbstractFuture
If AbstractFuture.interruptTask()
is also run during completion, AbstractFuture.afterDone()
runs after it.
The default implementation of this method in AbstractFuture
does nothing. This is
intended for very lightweight cleanup work, for example, timing statistics or clearing fields.
If your task does anything heavier consider, just using a listener with an executor.
