Dynamic delay value with repeatWhen()

Question

Right now I\'m implementing some polling logic with RxJava. I\'m supposed to poll an endpoint a number of times until it tells me to stop. Additionally, each response come

Answer 1

This is the solution I ended up using:

public static Observable createPollObservable(RetrofitService service, PollResponse response) {
    return Blah::shouldStopPolling(response)
        ? Observable.empty()
        : service
            .pollEndpoint()
            .delaySubscription(getPollDelay(response), TimeUnit.MILLISECONDS)
            .concatMap(response1 -> createPollObservable(service, response1)
                    .startWith(response1)
                    .takeUntil(Blah::shouldStopPolling)
            );
}

It instead uses recursion to always have the latest PollResponse object and also switches to delaySubscription() rather than repeatWhen().
