Abstract Value Members
- abstract def shouldRetry(lastState: S, lastEmittedElement: Option[A], lastFailure: Option[Throwable]): Option[(FiniteDuration, S)]
Determines whether the source should be restarted, and if so ((scala.Some$)), the backoff duration and the new state to restart from.
Determines whether the source should be restarted, and if so ((scala.Some$)), the backoff duration and the new state to restart from. Called after the current source has terminated normally or with an error.
- lastState
The state that was used to create the current source
- lastEmittedElement
The last element emitted by the current source and passed downstream. Downstream obviously need not yet have fully processed the element though. scala.None$ if the current source did not emit anything, even if previous sources have emitted elements.
- lastFailure
The error the current source failed with, if any.
