the Throwable that caused the restart to happen
Is called right AFTER restart on the newly created Actor to allow reinitialization after an Actor crash.
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.

Overridden callback. Prepends all messages in the stash to the mailbox, clears the stash, stops all children and invokes the postStop() callback.
the Throwable that caused the restart to happen
optionally the current message the actor processed when failing, if applicable
Is called on a crashed Actor right BEFORE it is restarted to allow clean up of resources before Actor is terminated.
Triggers an initial recovery, starting form a snapshot, if any, and replaying at most autoUpdateReplayMax
messages (following that snapshot).
This defines the initial actor behavior, it must return a partial function with the actor logic.

Is called when a message isn't handled by the current behavior of the actor 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()
