Trying to figure out how to chain partial functions with inheritance...

PartialFunctionChainingWithInheritance.scala

trait Parser { self: Actor =>

  def parse: PartialFunction[Opened, Unit]

  def receive: Receive = parse orElse(super.receive) andThen(_ => done())

  def collectWork: Receive

  def done(): Unit = {
    context become collectWork
    context.self ! Done
  }

}

trait StoryListParser extends Parser { self: Actor =>
  def parse = {
    case Opened(url, content) if url.getPath.endsWith("stories/") =>
      // ... PARSE LIST OF STORIES ...
  }
}

trait StoryParser extends Parser { self: Actor =>
  def parse = {
    case Opened(url, content) if url.getPath.matches("""stories\/[^\/]+$""") =>
    // ... PARSE INDIVIDUAL STORY ...
  }
}

class Job extends Actor with StoryListParser with StoryParser {
  def collectWork: Receive = {
    case Done => context.parent ! Done
  }
}
