Sequential composition for arbitrary number of calls in Vertx with Futures

Question

We use Futures in vertx in examples like:

Future fetchVehicle = getUserBookedVehicle(routingContext, client);

        fetchVehicle.compose         


        

Answer 1

Here's something handy. Hope it helps.

public static  Future> allOfFutures(List> futures) {
    return CompositeFutureImpl.all(futures.toArray(new Future[futures.size()]))
            .map(v -> futures.stream()
                    .map(Future::result)
                    .collect(Collectors.toList())
            );
}
