java.lang.Object

io.smallrye.mutiny.helpers.HalfSerializer

public final class HalfSerializer
extends Object

Methods to implement half-serialization: a form of serialization where onNext is guaranteed to be called from a single thread but onError or onComplete may be called from any threads.

Method Summary

Modifier and Type	Method and Description
static void	onComplete(org.reactivestreams.Subscriber<?> subscriber, AtomicInteger wip, AtomicReference<Throwable> container) Propagates the completion event or failure events (if a failure is stored in the container).
static void	onError(org.reactivestreams.Subscriber<?> subscriber, Throwable failure, AtomicInteger wip, AtomicReference<Throwable> container) Propagates the given failure if the downstream if possible (no work in progress) or accumulate it to the given failure container to be propagated by a concurrent onNext call.
static <T> void	onNext(org.reactivestreams.Subscriber<? super T> subscriber, T item, AtomicInteger wip, AtomicReference<Throwable> container) Propagates the given item if possible and terminates if there was a completion or failure event happening during the propagation.

Method Detail

onNext

public static <T> void onNext(org.reactivestreams.Subscriber<? super T> subscriber,
                              T item,
                              AtomicInteger wip,
                              AtomicReference<Throwable> container)

Propagates the given item if possible and terminates if there was a completion or failure event happening during the propagation. The item is drops is the downstream already got a terminal event.

Type Parameters:

T - the type of the item

Parameters:

subscriber - the downstream subscriber

item - the item to propagate downstream

wip - the serialization work-in-progress counter

container - the failure container

onError

public static void onError(org.reactivestreams.Subscriber<?> subscriber,
                           Throwable failure,
                           AtomicInteger wip,
                           AtomicReference<Throwable> container)

Propagates the given failure if the downstream if possible (no work in progress) or accumulate it to the given failure container to be propagated by a concurrent onNext call.

Parameters:

subscriber - the downstream subscriber

failure - the failure event to propagate

wip - the serialization work-in-progress counter

container - the failure container

onComplete

public static void onComplete(org.reactivestreams.Subscriber<?> subscriber,
                              AtomicInteger wip,
                              AtomicReference<Throwable> container)

Propagates the completion event or failure events (if a failure is stored in the container). If the event cannot be dispatched, a concurrent onNext will.

Parameters:

subscriber - the downstream subscriber

wip - the serialization work-in-progress counter

container - the failure container
