Class ParallelFromPublisher<T>

java.lang.Object

io.reactivex.rxjava3.parallel.ParallelFlowable<T>

io.reactivex.rxjava3.internal.operators.parallel.ParallelFromPublisher<T>

Type Parameters:

T - the value type

public final class ParallelFromPublisher<T>
extends ParallelFlowable<T>

Dispatches the values from upstream in a round robin fashion to subscribers which are ready to consume elements. A value from upstream is sent to only one of the subscribers.

ParallelFromPublisher

public ParallelFromPublisher(org.reactivestreams.Publisher<? extends T> source,
 int parallelism,
 int prefetch)

Method Details

parallelism

public int parallelism()

Description copied from class: ParallelFlowable

Returns the number of expected parallel Subscribers.

Specified by:

parallelism in class ParallelFlowable<T>

Returns:

the number of expected parallel Subscribers

subscribe

public void subscribe(org.reactivestreams.Subscriber<? super T>[] subscribers)

Description copied from class: ParallelFlowable

Subscribes an array of Subscribers to this ParallelFlowable and triggers the execution chain for all 'rails'.

Backpressure:

The backpressure behavior/expectation is determined by the supplied Subscriber.

Scheduler:

subscribe does not operate by default on a particular Scheduler.

Specified by:

subscribe in class ParallelFlowable<T>

Parameters:

subscribers - the subscribers array to run in parallel, the number of items must be equal to the parallelism level of this ParallelFlowable
