  • Type Parameters:
    T - the source value type
    R - the result value type
    All Implemented Interfaces:
    org.reactivestreams.Publisher<R>

    public final class SingleFlatMapPublisher<T,​R>
    extends Flowable<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.

        Description copied from class: Flowable
        Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Subscribers.

        There is no need to call any of the plugin hooks on the current Flowable instance or the Subscriber; all hooks and basic safeguards have been applied by Flowable.subscribe(Subscriber) before this method gets called.

        Specified by:
        subscribeActual in class Flowable<R>
        Parameters:
        downstream - the incoming Subscriber, never null
