Class AsyncSubscriber<T>

java.lang.Object

com.oath.cyclops.types.reactive.AsyncSubscriber<T>

Type Parameters:

T - Subscriber type

All Implemented Interfaces:

PushSubscriber<T>, org.reactivestreams.Subscriber<T>

public class AsyncSubscriber<T>
extends java.lang.Object
implements org.reactivestreams.Subscriber<T>, PushSubscriber<T>

A subscriber for Observable type Streams that avoid the overhead of applying backpressure. For backpressure aware event driven Streams Spouts.reactiveSubscriber()

    
          PushSubscriber<Integer> sub = Spouts.asyncSubscriber();

          //on a seperate thread
          for(int i=0;i<100;i++)
                sub.onNext(i);

            sub.onComplete();

          //on the main thread

          sub.stream()
             .peek(System.out::println)
             .collect(CyclopsCollectors.toList());

          //note JDK Stream based terminal operations may block the current thread
          //see ReactiveSeq#collectStream ReactiveSeq#foldAll for non-blocking alternatives
