T - the input and output value typepublic final class DirectProcessor<T> extends FluxProcessor<T,T>
This implementation signals an IllegalStateException if a Subscriber is not ready to receive a value due to not requesting enough.
The implementation ignores Subscriptions push via onSubscribe.
A terminated DirectProcessor will emit the terminal signal to late subscribers.

CoreSubscriberSubscriber.onNext(Object) before
calling Subscription.request(long). Should further onNext related
state modification occur, thread-safety will be required.
Note that an invalid request <= 0 will not produce an onError and
will simply be ignored or reported through a debug-enabled
Logger.

public void subscribe(CoreSubscriber<? super T> actual)
FluxPublisher.subscribe(Subscriber) that will bypass
Hooks.onLastOperator(Function) pointcut.
In addition to behave as expected by Publisher.subscribe(Subscriber)
in a controlled manner, it supports direct subscribe-time Context passing.
