abstract class AbstractActorWithUnrestrictedStash extends AbstractActor with UnrestrictedStash
Java API: compatible with lambda expressions
Actor base class with Stash that does not enforce any mailbox type. The mailbox of the actor has to be configured
manually. See akka.actor.AbstractActorWithStash for details on how Stash works.
