Protocols in Akka Typed

Akka Typed is an evolution of the untyped Akka actor implementation to support channel types: most importantly, the ActorRef now is parameterized with the type of messages it accepts. This has several other consequences that we discuss in this lecture.

The use of more precise types within actor interactions is then demonstrated on a small example, including how to set up a typed actor system and how to handle fully typed responses, i.e. continuations of the protocol throughout the full interchange.
