The Flow.Processor interface

The Flow.Processor interface can serve as both a Subscriber and a Publisher. The implementation is provided here:

    static interface Flow.Processor<T,R> extends Flow.Subscriber<T>,     Flow.Publisher<R>

This interface takes two arguments--the subscribed item type <T> and the published item type <R>. It does not have its own methods, but does inherit the following method from java.util.concurrent.Flow.Publisher:

  • void subscribe(Flow.Subscriber<? super T> subscriber)

Flow.Processor also inherits the following methods from the java.util.concurrent.Flow.Subscriber interface:

  • void onComplete()
  • void onError(Throwable throwable)
  • void onNext(T item)
  • void onSubscribe(Flow.Subscription subscription)
