akka.kernel
Interface Bootable

public interface Bootable

To use the microkernel at least one 'boot class' needs to be specified. A boot class implements this interface (Bootable) and must have an empty default constructor.

ActorSystems can be created within the boot class.

An example of a simple boot class:

 class BootApp extends Bootable {
   val system = ActorSystem("app")

   def startup = {
     system.actorOf(Props[FirstActor]) ! FirstMessage
   }

   def shutdown = {
     system.shutdown()
   }
 }
 

Boot classes are specified as main arguments to the microkernel.

For example, using the akka script an application can be started with the following at the command line:

 bin/akka org.app.BootApp
