asDeferred
Returns a Deferred that is completed or failed by this
ListenableFuture.
Completion is non-atomic between the two promises.
Cancellation is propagated bidirectionally.
When this
ListenableFuture
completes (either successfully or exceptionally) it will try to complete the returned Deferred
with the same value or exception. This will succeed, barring a race with cancellation of the Deferred
.
When this
ListenableFuture
is successfully cancelled, it will cancel the returned Deferred
.
When the returned Deferred
is cancelled, it will try to propagate the cancellation to this
ListenableFuture
. Propagation will succeed, barring a race with the ListenableFuture
completing normally. This is the only case in which the returned Deferred
will complete with a different outcome than this
ListenableFuture
.
