RxJava 2 2.2.21 · io.reactivex.subjects.Subject

Represents an Observer and an Observable at the same time, allowing multicasting events from a single source to multiple child Observers.

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