Method Details

parallelism

public int parallelism()

Description copied from class: ParallelFlowable

Returns the number of expected parallel Subscribers.

Specified by:

parallelism in class ParallelFlowable<R>

Returns:

the number of expected parallel Subscribers

subscribe

public void subscribe(org.reactivestreams.Subscriber<? super R>[] 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<R>

Parameters:

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