Method Details

org$apache$pekko$actor$StashSupport$_setter_$mailbox_$eq

protected void org$apache$pekko$actor$StashSupport$_setter_$mailbox_$eq(DequeBasedMessageQueueSemantics x$1)

Specified by:

org$apache$pekko$actor$StashSupport$_setter_$mailbox_$eq in interface StashSupport

postStop

public void postStop()

Description copied from interface: UnrestrictedStash

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.

Specified by:

postStop in interface Actor

Specified by:

postStop in interface FSM<S,D>

Specified by:

postStop in interface UnrestrictedStash
