  6. object Escalate extends Directive with Product with Serializable

    Escalates the failure to the supervisor of the supervisor, by rethrowing the cause of the failure, i.

  7. object Restart extends Directive with Product with Serializable

    Discards the old Actor instance and replaces it with a new, then resumes message processing.

  8. object Resume extends Directive with Product with Serializable

    Resumes message processing for the failed Actor

  9. object Stop extends Directive with Product with Serializable

    Stops the Actor

  12. final val defaultDecider: Decider

    When supervisorStrategy is not specified for an actor this Decider is used by default in the supervisor strategy.

    When supervisorStrategy is not specified for an actor this Decider is used by default in the supervisor strategy. The child will be stopped when akka.actor.ActorInitializationException, akka.actor.ActorKilledException, or akka.actor.DeathPactException is thrown. It will be restarted for other Exception types. The error is escalated if it's a Throwable, i.e. Error.

  13. final val defaultStrategy: SupervisorStrategy

    When supervisorStrategy is not specified for an actor this is used by default.

    When supervisorStrategy is not specified for an actor this is used by default. OneForOneStrategy with decider defined in #defaultDecider.

    Java API: Returning this directive escalates the failure to the supervisor of the supervisor, by rethrowing the cause of the failure, i.e. the supervisor fails with the same exception as the child.

  21. def makeDecider(func: JDecider): Decider

    Converts a Java Decider into a Scala Decider

  22. def makeDecider(flat: Iterable[(Class[_ <: Throwable], Directive)]): Decider

    Decider builder for Iterables of cause-directive pairs, e.

    Decider builder for Iterables of cause-directive pairs, e.g. a map obtained from configuration; will sort the pairs so that the most specific type is checked before all its subtypes, allowing carving out subtrees of the Throwable hierarchy.

  23. def makeDecider(trapExit: Iterable[Class[_ <: Throwable]]): Decider

    Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.

  24. def makeDecider(trapExit: Seq[Class[_ <: Throwable]]): Decider

    Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.

  28. def restart: Restart.type

    Java API: Returning this directive resumes message processing for the failed Actor

  30. implicit def seqCauseDirective2Decider(trapExit: Iterable[(Class[_ <: Throwable], Directive)]): Decider

    Implicit conversion from Seq of Cause-Directive pairs to a Decider.

    Implicit conversion from Seq of Throwables to a Decider.

    Implicit conversion from Seq of Throwables to a Decider. This maps the given Throwables to restarts, otherwise escalates.

  32. def stop: Stop.type

    Java API: Returning this directive stops the Actor

  33. final val stoppingStrategy: SupervisorStrategy

    This strategy resembles Erlang in that failing children are always terminated (one-for-one).
