io.reactivex.processors

Class FlowableProcessor

java.lang.Object

io.reactivex.Flowable

io.reactivex.processors.FlowableProcessor

Type Parameters:

T - the item value type

All Implemented Interfaces:

FlowableSubscriber, Processor, Publisher, Subscriber

Direct Known Subclasses:

AsyncProcessor, BehaviorProcessor, MulticastProcessor, PublishProcessor, ReplayProcessor, UnicastProcessor

public abstract class FlowableProcessor
extends Flowable
implements Processor, FlowableSubscriber

Represents a Subscriber and a Flowable (Publisher) at the same time, allowing multicasting events from a single source to multiple child Subscribers.

All methods except the onSubscribe, onNext, onError and onComplete are thread-safe. Use toSerialized() to make these methods thread-safe as well.
