Actors in Scala Philipp Haller, Frank Sommers

Akka actors unit testing with Scala I'm fairly new to Scala so please be gentle. One of the key performance attributes for Actors is the speed with which messages can be consumed and processed. WebSockets Echo Using Play, Scala, and Actors, Part I. I've been experimenting in my spare time with the Scala actors library for about a year now. Actors in Scala is the authoritative guide to programming with the actors framework of Scala's standard library, co-written by the creator and lead maintainer, Philipp Haller. In Chapter 30 of "Programming in Scala" Scala's Actors is described in detail. In the app I'm building, I'm using Akka actors and I want to write some unit tests. Class Sieve(val p: Int) extends Actor {. There's a perfectly good example of a simple chat room server using the Play Framework, WebSockets, and Actors. Some syntax notes for the Scala newbs: ;'s are optional, Unit is like void in Java, array access is with () not [], ! Is the Erlang send operator ported into the actor library (it's just a method call on a method named “!”). I'm working with web service clients, and they are slow on the first call. A well known feature of Scala is it support for message passing concurrency via Actors similar to Erlang. Instead of always creating a brand new one, I would like to use actors and have say 5 actors to wrap the web service clients.
