Remember that the the type of receive method is alias for
PartialFunction[Any, Unit] and you can compose partial functions using
orElse[1]
You can defined several message handling function in your base class, and
them mix & match them in derived classes:
scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> receive() {
return behaviorOne.orElse(behaviorTwo).orElse(behaviorThree);
}
Of course ordering matters, unless the domains of your functions (handled
message sets) are fully disjoint.
