  • Field Details

      public static final SupervisorStrategy$ MODULE$
      Static reference to the singleton instance of this Scala object.

  • Constructor Details

    • SupervisorStrategy$

      public SupervisorStrategy$()

  • Method Details

    • resume

      public SupervisorStrategy.Resume$ resume()
      Java API: Returning this directive resumes message processing for the failed Actor

    • resume

      public SupervisorStrategy.Directive resume(Logging.LogLevel logLevel)
      Returning this directive resumes message processing for the failed Actor.

      Parameters:
      logLevel - Log level which will be used to log the failure

    • restart

      public SupervisorStrategy.Restart$ restart()
      Java API: Returning this directive discards the old Actor instance and replaces it with a new, then resumes message processing.

    • restart

      public SupervisorStrategy.Directive restart(Logging.LogLevel logLevel)
      Returning this directive discards the old Actor instance and replaces it with a new, then resumes message processing.

      Parameters:
      logLevel - Log level which will be used to log the failure

    • stop

      public SupervisorStrategy.Stop$ stop()
      Java API: Returning this directive stops the Actor

    • stop

      public SupervisorStrategy.Directive stop(Logging.LogLevel logLevel)
      Returning this directive stops the Actor

      Parameters:
      logLevel - Log level which will be used to log the failure

    • escalate

      public SupervisorStrategy.Escalate$ escalate()
      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.

    • defaultDecider

      public final scala.PartialFunction<Throwable,SupervisorStrategy.Directive> defaultDecider()
      When supervisorStrategy is not specified for an actor this Decider is used by default in the supervisor strategy. The child will be stopped when pekko.actor.ActorInitializationException, pekko.actor.ActorKilledException, or pekko.actor.DeathPactException is thrown. It will be restarted for other Exception types. The error is escalated if it's a Throwable, i.e. Error.

    • defaultStrategy

      public final SupervisorStrategy defaultStrategy()
      When supervisorStrategy is not specified for an actor this is used by default. OneForOneStrategy with decider defined in defaultDecider().

    • stoppingStrategy

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

    • seqThrowable2Decider

      public scala.PartialFunction<Throwable,SupervisorStrategy.Directive> seqThrowable2Decider(scala.collection.immutable.Seq<Class<? extends Throwable>> trapExit)
      Implicit conversion from Seq of Throwables to a Decider. This maps the given Throwables to restarts, otherwise escalates.

    • makeDecider

      public scala.PartialFunction<Throwable,SupervisorStrategy.Directive> makeDecider(scala.collection.immutable.Seq<Class<? extends Throwable>> trapExit)
      Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.

    • makeDecider

      public scala.PartialFunction<Throwable,SupervisorStrategy.Directive> makeDecider(Iterable<Class<? extends Throwable>> trapExit)
      Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.

    • makeDecider

      public scala.PartialFunction<Throwable,SupervisorStrategy.Directive> makeDecider(scala.collection.Iterable<scala.Tuple2<Class<? extends Throwable>,SupervisorStrategy.Directive>> flat)
      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.

    • makeDecider

      public scala.PartialFunction<Throwable,SupervisorStrategy.Directive> makeDecider(Function<Throwable,SupervisorStrategy.Directive> func)
      Converts a Java Decider into a Scala Decider
