I am following book which uses subscriber.isUnsubscribed() but it is no longer available in version 2.0. Can somebody guide me how to rewrite this code to be able to use isUnsubscribed check in the Observable lambda?

Observable<BigInteger> naturalNumbers = Observable.create(
    subscriber -> {
        Runnable r = () -> {
            BigInteger i = ZERO;
            while (!subscriber.isUnsubscribed()) {
                subscriber.onNext(i);
                i = i.add(ONE);
            }
        };
        new Thread(r).start();
    });


Subscription subscription = naturalNumbers.subscribe(x -> log(x));
//after some time...
subscription.unsubscribe();

What are you trying to do there? – Progman Feb 02 '19 at 13:48

This is an example from the 'Infinite streams' chapter from Tomasz Nurkiewicz book on rxjava. I have updated code to the exact one from the book. – mike Feb 02 '19 at 14:06
I am thinking that Flowable is the correct use here, but does that mean that Observable from 2.0 no longer supports checking whether there is a subscription to it? – mike Feb 02 '19 at 14:06

Isn't it `isDisposed`? – EpicPandaForce Feb 02 '19 at 14:11
