io.reactivex.rxjava3.subscribers

Class SerializedSubscriber

java.lang.Object

io.reactivex.rxjava3.subscribers.SerializedSubscriber

Type Parameters:

T - the value type

All Implemented Interfaces:

FlowableSubscriber, Subscriber, Subscription

public final class SerializedSubscriber
extends Object
implements FlowableSubscriber, Subscription

Serializes access to the Subscriber.onNext(Object), Subscriber.onError(Throwable) and Subscriber.onComplete() methods of another 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 Subscription before any of the other methods are called.

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

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

Constructor Detail

SerializedSubscriber

public SerializedSubscriber(SubscriberT> downstream)

Construct a SerializedSubscriber by wrapping the given actual Subscriber.

Parameters:

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

SerializedSubscriber

public SerializedSubscriber(@NonNull
                            @NonNull SubscriberT> actual,
                            boolean delayError)

Construct a SerializedSubscriber by wrapping the given actual 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 Detail

onSubscribe

public void onSubscribe(@NonNull
                        @NonNull Subscription s)

Description copied from interface: FlowableSubscriber

Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling 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.
