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
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.

-
subscribe
Description copied from class:ParallelFlowable
Subscribes an array ofSubscriber
s to thisParallelFlowable
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 particularScheduler
.
- Specified by:
subscribe
in classParallelFlowable<T>
- Parameters:
subscribers
- the subscribers array to run in parallel, the number of items must be equal to the parallelism level of thisParallelFlowable
