RxJava2 - Mutlicasting Singles, Maybes and Completables?

Question

What is the recommended way to multicast single player, Maybes and Completables? Is it recommended that you simply translate them into standard observables for multicast?

    Observable<String> strings =
            Observable.just("Alpha", "Beta", "Gamma", "Delta", "Epsilon");

    Observable<Integer> lengths = strings.map(String::length);

    ConnectableObservable<List<Integer>> lengthsList = 
            lengths.toList().toObservable().publish();

I am a little surprised that not ConnectableSingle, ConnectableMaybeand ConnectableCompletable. What are the reasons for this? Isn't it worth the effort for development?

Answer 1

I think .toObservable().publish()this is the way to go.
