public interface ConditionalSubscriber<@NonNull T>
extends FlowableSubscriber<T>

A FlowableSubscriber with an additional tryOnNext(Object) method that tells the caller the specified value has been accepted or not.

This allows certain queue-drain or source-drain operators to avoid requesting 1 on behalf of a dropped value.

Since:

3.1.1
