use of io.reactivex.Flowable in project rxjava2-jdbc by davidmoten.

the class NonBlockingPool method createMembers.

private Flowable<Member<T>> createMembers() {
    List<Member<T>> ms = IntStream.range(1, maxSize + 1).mapToObj(//
    n -> memberFactory.create(NonBlockingPool.this)).collect(Collectors.toList());
    Flowable<Member<T>> baseMembers = //
    Flowable.fromIterable(ms).doOnRequest(n -> log.debug("requested={}", n));
    Flowable<Member<T>> returnedMembers = //
    subject.toSerialized().toFlowable(BackpressureStrategy.BUFFER);
    // use CAS loop to handle a race with close
    while (true) {
        List<Member<T>> l = list.get();
        if (l == null) {
            return Flowable.error(new PoolClosedException());
        } else if (list.compareAndSet(Collections.emptyList(), ms)) {
