Futures.immediateScheduledFuture() #810

Open gissuebot opened 9 years ago

Original issue created by cow...@bbs.darktech.org on 2011-12-02 at 07:45 PM

I'd like to request the ability to construct a ScheduledFuture with an immediate value set.

Use-case: initializing ScheduledFuture fields with a default value.

When do you need to construct such a Future?

(If we do do this, we need to think about what getDelay and compareTo will do.)

Here is my use-case:

I have a class with a ScheduledFuture field. When a user clicks a button I do the following:

  1. Cancel the future associated with the field
  2. Schedule a new operation, and store the associated future in the field

As you can see, the first time around the field needs a "null object".

I am expecting getDelay() to return 0 since the future is supposed to represent a completed operation. I am expecting compareTo() to return:

(int) Math.signum(-other.getDelay(TimeUnit.MILLISECONDS))
