Interface SegmentCompletionPublisher<R>

Type Parameters:

R - value type

All Superinterfaces:

org.reactivestreams.Publisher<R>

All Known Subinterfaces:

SegmentAwarePublisher<R>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SegmentCompletionPublisher<R>
extends org.reactivestreams.Publisher<R>

A Publisher that also notifies in a thread safe manner when a segment has sent all values upstream. To more specifically detail the guarantee, the accept method of the provided IntConsumer will be invoked serially inline with onNext, onError, onComplete and will only be invoked after all values from the given segment have already been notified via onNext). Note that there is no guarantee that the previous values was from the given segment, only that all have been notified prior.

If segment completion is not needed, use the {@link Publisher#subscribe(Subscriber)} or provided {@link #EMPTY_CONSUMER} as the argument to the {@link #subscribe(Subscriber, IntConsumer)} method. This allows implementors to optimize for the case when segment completion is not needed as this may require additional overhead.
