23/**
24 * A {@link ScheduledExecutorService} that returns {@link ListenableFuture}
25 * instances from its {@code ExecutorService} methods.  Futures returned by the
26 * {@code schedule*} methods, by contrast, need not implement {@code
27 * ListenableFuture}.  (To create an instance from an existing {@link
28 * ScheduledExecutorService}, call {@link
29 * MoreExecutors#listeningDecorator(ScheduledExecutorService)}.
30 *
31 * <p>TODO(cpovirk): make at least the one-time schedule() methods return a
32 * ListenableFuture, too? But then we'll need ListenableScheduledFuture...
