I'm struggling again with the types in Java. I want to group elements in a
Flow, and call a processing step like this:
final Flow<List<VerwerkingsResultaat>, Integer, BoxedUnit>
saveOrganisatiesFlow = Flow.of(List.class).mapAsync(4, new
Function<List<VerwerkingsResultaat>, Future<Integer>>() {
@Override
public Future<Integer> apply(List<VerwerkingsResultaat>
verwerkingsResultaten) throws Exception {
return Futures.successful(1);
}
});
Future<BoxedUnit> future = recordSource.grouped(1000)
.via(saveOrganisatiesFlow)
.runWith(printingSink, materializer);
Of course there is a collission between the type List<VerwerkingsResultaat>
and the Flow.of(List.class). How can I group elements like this in Java?
