ExtensionKey

abstract class ExtensionKey[T <: Extension] extends ExtensionId[T] with ExtensionIdProvider

This is a one-stop-shop if all you want is an extension which is constructed with the ExtendedActorSystem as its only constructor argument:

object MyExt extends ExtensionKey[Ext]

class Ext(system: ExtendedActorSystem) extends Extension {
  ...
}

Java API:

public class MyExt extends Extension {
  public static final ExtensionKey<MyExt> key = new ExtensionKey<MyExt>(MyExt.class);

  public MyExt(ExtendedActorSystem system) {
    ...
  }
}

Note: Don't use this class if the extension is written in Scala and consumed in Eclipse Java projects. JDT has problems resolving correct type for the get method.
