3. trait RouteSubscriptionSupport extends LazyLogging

   

   The 'RouteSubscriptionSupport' exposes a directive exists to integrate existing routes with an Exchange.

   The 'RouteSubscriptionSupport' exposes a directive exists to integrate existing routes with an Exchange.

   Consider some basic route:

   post(path("foo")) { ... }

   We want to be able to integrate it with an exchange to make it a reactive, work-pulling route. We also want that to be non-intrusive. A client of our basic route shouldn't be forced to go via the Exchange to use our endpoint; it should work the same with or without the exchange.

   To accomplish this, we'll need to know: 1) The exchange from which to pull more work 2) the subscription key used to request the next work item 3) a means to identify whether the given request was made as a result of a match on the exchange (as opposed to just being hit directly) 4) to know when the response is complete

4. case class SubscriptionGroup(subscriptions: List[WorkSubscription], initialExecutionSubscription: Int) extends Product with Serializable

   

   A subscription group represents work subscriptions which will reference each other.

5. class WithSubscriptionWord extends AnyRef

   

   Class just to support a DSL so you can have:

6. case class WorkContext[T](exchange: Exchange, routes: DynamicWorkerRoutes, subscriptionKey: Option[SubscriptionKey], subscription: WorkSubscription, requestContext: RequestContext, request: T)(implicit evidence$1: FromRequestUnmarshaller[T]) extends Product with Serializable

   

   Wraps the input to a computation, allowing the computation (mostly) to call 'request(n)' so it can request more work.

   Wraps the input to a computation, allowing the computation (mostly) to call 'request(n)' so it can request more work.

   This class is analogous to a Subscription in Reactive Streams

   T

   the request type

   exchange

   the interface to an exchange so it can request more work or even cancel the subscription or return the job

   routes

   the worker routes containing this handler

   subscription

   the details of the subscription

   requestContext

   the http request context which contains the original HttpRequest, etc

   request

   the unmarshalled handler input
