mapEmpty

open fun <V : Any> mapEmpty(): Future<V>

Map the result of a future to null.

This is a conveniency for future.map((T) null) or future.map((Void) null).

When this future succeeds, null will complete the future returned by this method call.

When this future fails, the failure will be propagated to the returned future.

Return
the mapped future
