ObserverAsSubscriber

Wraps a Observer instance into an Subscriber instance. The resulting subscriber respects the Reactive Streams contract.

Given that when emitting Observer.onNext calls, the call may pass asynchronous boundaries, the emitted events need to be buffered. The requestCount constructor parameter also represents the buffer size.

To create an instance, ObserverAsSubscriber.apply must be used:

// uses the default requestCount of 128
val subscriber = ObserverAsSubscriber(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")
  }
})
