Example 16 with Observer

use of io.reactivex.Observer in project RxJava by ReactiveX.

the class ObservableSubscriberTest method testOnStartCalledOnceViaLift.

@Test

    final AtomicInteger c = new AtomicInteger();
    Observable.just(1, 2, 3, 4).lift(new ObservableOperator<Integer, Integer>() {

        @Override
