Overridden callback.
Overridden callback. Prepends all messages in the stash to the mailbox and clears the stash. Must be called when overriding this method, otherwise stashed messages won't be propagated to DeadLetters when actor stops.

Recommended convention is to call this method if the message isn't handled in #onReceive (e.g. unknown message type). By default it fails with either a akka.actor.DeathPactException (in case of an unhandled akka.actor.Terminated message) or publishes an akka.actor.UnhandledMessage to the actor's system's akka.event.EventStream.

Prepends all messages in the stash to the mailbox, and then clears the stash.
Messages from the stash are enqueued to the mailbox until the capacity of the
mailbox (if any) has been reached. In case a bounded mailbox overflows, a
MessageQueueAppendFailedException
is thrown.
The stash is guaranteed to be empty after calling unstashAll()

that does not enforce any mailbox type. The proper mailbox has to be configured manually, and the mailbox should extend the akka.dispatch.DequeBasedMessageQueueSemantics marker trait. See akka.actor.UntypedActorWithStash for details on howStash
works.(Since version 2.5.0) Use AbstractActorWithUnrestrictedStash instead of UntypedActorWithUnrestrictedStash.
