SynchronousSubscriberAsReactiveSubscriber

final class SynchronousSubscriberAsReactiveSubscriber[T] extends org.reactivestreams.Subscriber[T]

Wraps a SynchronousObserver instance into a org.reactivestreams.Subscriber instance. The resulting subscriber respects the Reactive Streams contract.

Given that we can guarantee a SynchronousObserver is used, then no buffering is needed and thus the implementation is very efficient.

To create an instance, SynchronousSubscriberAsReactiveSubscriber must be used: 

// uses the default requestCount of 128
val subscriber = SynchronousSubscriberAsReactiveSubscriber(new Observer[Int] {
  private[this] var sum = 0

  def onNext(elem: Int) = {
    sum += elem
    Continue
  }

  def onError(ex: Throwable) = {
    logger.error(ex)
  }

  def onComplete() = {
    logger.info("Stream completed")
  }
})
