Example 51 with Predicate

use of io.reactivex.rxjava3.functions.Predicate in project RxJava by ReactiveX.

the class ObservableRetryTest method noCancelPreviousRepeatWhen.

@Test

            }
            return Observable.just(1);

Example 52 with Predicate

Example 53 with Predicate

use of io.reactivex.rxjava3.functions.Predicate in project RxJava by ReactiveX.

    Maybe<Integer> o = Observable.just(1).filter(new Predicate<Integer>() {

        @Override
        public boolean test(Integer t1) {
