RxJava 3 3.1.8 · io.reactivex.rxjava3.observers.SerializedObserver

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

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

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