Bootable

trait Bootable extends AnyRef

To use the microkernel at least one 'boot class' needs to be specified. A boot class implements this interface (akka.kernel.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.terminate()
  }
}

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
