Java API (not recommended): Callback for the Future.filter operation that creates a new Future which will conditionally contain the success of another Future.
Unfortunately it is not possible to express the type of a Scala filter in Java: Function1[T, Boolean], where “Boolean” is the primitive type. It is possible to use
Future.filter
by constructing such a function indirectly:However,
Future.filter
exists mainly to support Scala’s for-comprehensions, thus Java users should preferFuture.map
, translating non-matching values to failure cases.
