# 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
