public final Class SingleFlatMapPublisher<T, R>

A Flowable that emits items based on applying a specified function to the item emitted by the source Single, where that function returns a Publisher.

Backpressure:: The returned Flowable honors the backpressure of the downstream consumer and the Publisher returned by the mapper function is expected to honor it as well.
Scheduler:: flatMapPublisher does not operate by default on a particular Scheduler.

onSuccess	back to summary
public void onSuccess(S value) Implements io.reactivex.rxjava3.core.SingleObserver.onSuccess. Doc from io.reactivex.rxjava3.core.SingleObserver.onSuccess. Notifies the `SingleObserver` with a single item and that the `Single` has finished sending push-based notifications. The `Single` will not call this method if it calls `onError`.

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

public void request(long n)

Implements org.reactivestreams.Subscription.request.
