Ultimately I was able to find a group of related directives.
So this for example works:
...
public Route route() {
return parameterOptional("name", optName -> {
String name = optName.orElse(_defaultName);
return parameterOptional("times", optTimes -> {
int times = optTimes.map(Integer::parseInt).orElse(1);
final Marshaller<Saying, RequestEntity> marshaller =
Jackson.<Saying>marshaller();
return completeOKWithFuture(futureSayHello(name, times), marshaller);
});
});
}
//convert the Observable to a completeionStage
public CompletionStage<Saying> futureSayHello(final String name, final int
times) {
...
