SynchronousObserverAsSubscriber
Wraps a SynchronousObserver instance into a Subscriber instance.
Wraps a SynchronousObserver instance into a 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, SynchronousObserverAsSubscriber.apply must be used:
// uses the default requestCount of 128 val subscriber = SynchronousObserverAsSubscriber(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") } })
the observer instance that will get wrapped into a Subscriber
the parameter passed to Subscription.request
the execution context needed for processing asynchronous Future results
