.Note that the returned action may complete after the reference has been successfully set: use
F.start(r.complete)
if you want asynchronous behaviour.If this
Deferred
has already been completed, the returned action immediately fails with anIllegalStateException
. In the uncommon scenario where this behavior is problematic, you can handle failure explicitly usingattempt
