Examples with DROP - reactor.core.publisher.FluxSink.OverflowStrategy.DROP

Example 1 with DROP

use of reactor.core.publisher.FluxSink.OverflowStrategy.DROP in project reactor-core by reactor.

the class FluxSubscribeOnTest method forceScheduledRequests.

@Test
public void forceScheduledRequests() {
    Flux<Integer> test = Flux.<Integer>create(sink -> {
        for (int i = 1; i < 1001; i++) {
            sink.next(i);
            try {
                Thread.sleep(1);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        sink.complete();
    }, DROP).map(Function.identity()).subscribeOn(Schedulers.single(), true).publishOn(Schedulers.elastic());
    AtomicInteger count = new AtomicInteger();
    StepVerifier.create(test).thenConsumeWhile(t -> count.incrementAndGet() != -1).expectComplete().verify(Duration.ofSeconds(5));
    assertThat(count.get()).isEqualTo(Queues.SMALL_BUFFER_SIZE);
}

Example 2 with DROP

use of reactor.core.publisher.FluxSink.OverflowStrategy.DROP in project reactor-core by reactor.

the class FluxSubscribeOnTest method forceNoScheduledRequests.

@Test
public void forceNoScheduledRequests() {
    Flux<Integer> test = Flux.<Integer>create(sink -> {
        for (int i = 1; i < 1001; i++) {
            sink.next(i);
            try {
                Thread.sleep(1);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        sink.complete();
    }, DROP).map(Function.identity()).subscribeOn(Schedulers.single(), false).publishOn(Schedulers.elastic());
    AtomicInteger count = new AtomicInteger();
    StepVerifier.create(test).thenConsumeWhile(t -> count.incrementAndGet() != -1).expectComplete().verify(Duration.ofSeconds(5));
    assertThat(count.get()).isGreaterThan(Queues.SMALL_BUFFER_SIZE);
}
