I have server actor running in the background. The basic operation of the server actor is to get a key and a value pair. Once it receives the pair, it stores it in a map and returns it when asked. Now, I have a client actor. I want to the connect to the server actor using actorSelection() method. But I am confused with the parameters it takes. Can anyone help me understand what parameters it takes ?
Server side:- Actor System: actorSystem Server Actor: akkademy-db
Client side:- Actor System: LocalSystem
You didn't mention that your scenario is from the book Learning Akka. As stated in the book, the client can obtain an ActorSelection of the server with the following:
ActorSelection remoteDb = system.actorSelection("akka.tcp://akkademy@" + remoteAddress + "/user/akkademy-db")
The template for the path, as the documentation describes, is the following:
akka.<protocol>://<actor system name>@<hostname>:<port>/<actor path>
Using the template, here's a breakdown of the ActorSelection path to the server:
"akka.tcp://akkademy@" + remoteAddress + "/user/akkademy-db"
// tcp --> protocol
// akkademy --> actor system name
// remoteAddress --> hostname:port
// /user/akkademy-db --> actor path
Read the documentation for more information.
