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

You could use the side effect operator doOnNext to update a delay variable and then use that in your repeatWhen

int pollDelay = 5000;

service.pollEndpoint()
.doOnNext(pollResponse -> pollDelay=pollResponse.getDelay())
.repeatWhen(observable -> observable.delay(pollDelay, TimeUnit.MILLISECONDS))
.takeUntil(Blah::shouldStopPolling);
