onSubscribe	back to summary
public void onSubscribe(Subscription s) Implements io.reactivex.FlowableSubscriber.onSubscribe. Doc from io.reactivex.FlowableSubscriber.onSubscribe. Implementors of this method should make sure everything that needs to be visible in `onNext(Object)` is established before calling `Subscription#request(long)`. In practice this means no initialization should happen after the `request()` call and additional behavior is thread safe in respect to `onNext`. Invoked after calling `Publisher#subscribe(Subscriber)`. No data will start flowing until `Subscription#request(long)` is invoked. It is the responsibility of this `Subscriber` instance to call `Subscription#request(long)` whenever more data is wanted. The `Publisher` will send notifications only in response to `Subscription#request(long)`. Parameters s:Subscription Doc from org.reactivestreams.Subscriber.onSubscribe. the `Subscription` that allows requesting data via `Subscription#request(long)` Annotations @Override

request back to summary

request	back to summary
public void request(long n) Implements org.reactivestreams.Subscription.request. Doc from org.reactivestreams.Subscription.request. No events will be sent by a `Publisher` until demand is signaled via this method. It can be called however often and whenever needed—but if the outstanding cumulative demand ever becomes Long.MAX_VALUE or more, it may be treated by the `Publisher` as "effectively unbounded". Whatever has been requested can be sent by the `Publisher` so only signal demand for what can be safely handled. A `Publisher` can send less than is requested if the stream ends but then must emit either `Subscriber#onError(Throwable)` or `Subscriber#onComplete()`. Parameters n:long the strictly positive number of elements to requests to the upstream `Publisher` Annotations @Override
