Class SerializedSubscriber<T>

java.lang.Object

io.reactivex.rxjava4.subscribers.SerializedSubscriber<T>

Type Parameters:

T - the value type

All Implemented Interfaces:

FlowableSubscriber<T>, Flow.Subscriber<T>, Flow.Subscription

public final class SerializedSubscriber<T>
extends Object
implements FlowableSubscriber<T>, Flow.Subscription

Serializes access to the Flow.Subscriber.onNext(Object), Flow.Subscriber.onError(Throwable) and Flow.Subscriber.onComplete() methods of another Flow.Subscriber.

Note that onSubscribe(Subscription) is not serialized in respect of the other methods so make sure the onSubscribe is called with a non-null Flow.Subscription before any of the other methods are called.

The implementation assumes that the actual Subscriber's methods don't throw.

Constructor	Description
SerializedSubscriber(@NonNull Flow.Subscriber<? super T> actual, boolean delayError)	Construct a SerializedSubscriber by wrapping the given actual Flow.Subscriber and optionally delaying the errors till all regular values have been emitted from the internal buffer.
SerializedSubscriber(Flow.Subscriber<? super T> downstream)	Construct a SerializedSubscriber by wrapping the given actual Flow.Subscriber.

Constructor Details

SerializedSubscriber

public SerializedSubscriber(Flow.Subscriber<? super T> downstream)

Construct a SerializedSubscriber by wrapping the given actual Flow.Subscriber.

Parameters:

downstream - the actual Subscriber, not null (not verified)

SerializedSubscriber

public SerializedSubscriber(@NonNull
 @NonNull Flow.Subscriber<? super T> actual,
 boolean delayError)

Construct a SerializedSubscriber by wrapping the given actual Flow.Subscriber and optionally delaying the errors till all regular values have been emitted from the internal buffer.

Parameters:

actual - the actual Subscriber, not null (not verified)

delayError - if true, errors are emitted after regular values have been emitted

Method Details

onSubscribe

public void onSubscribe(@NonNull
 @NonNull Flow.Subscription s)

Description copied from interface: FlowableSubscriber

Implementors of this method should make sure everything that needs to be visible in Flow.Subscriber.onNext(Object) is established before calling Flow.Subscription.request(long). In practice this means no initialization should happen after the request() call and additional behavior is thread safe in respect to onNext.
