An object
that implements this interface has an associated delay. Typically, it
is some kind of task, such as a Callable, that has
been scheduled to execute at some future time. getdelay(
) returns the remaining time, measured in the specified
TimeUnit. If no time remains, geTDelay(
) should return zero or a negative value. See
ScheduledFuture and DelayQueue.
