Method Summary

Modifier and Type	Method	Description
scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive>	defaultDecider()	When supervisorStrategy is not specified for an actor this Decider is used by default in the supervisor strategy.
SupervisorStrategy	defaultStrategy()	When supervisorStrategy is not specified for an actor this is used by default.
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.
scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive>	makeDecider(java.lang.Iterable<java.lang.Class<? extends java.lang.Throwable>> trapExit)	Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.
scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive>	makeDecider(Function<java.lang.Throwable,SupervisorStrategy.Directive> func)	Converts a Java Decider into a Scala Decider
scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive>	makeDecider(scala.collection.immutable.Seq<java.lang.Class<? extends java.lang.Throwable>> trapExit)	Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.
scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive>	makeDecider(scala.collection.Iterable<scala.Tuple2<java.lang.Class<? extends java.lang.Throwable>,SupervisorStrategy.Directive>> flat)	Decider builder for Iterables of cause-directive pairs, e.g.
SupervisorStrategy.Restart$	restart()	Java API: Returning this directive discards the old Actor instance and replaces it with a new, then resumes message processing.
SupervisorStrategy.Directive	restart(Logging.LogLevel logLevel)	Returning this directive discards the old Actor instance and replaces it with a new, then resumes message processing.
SupervisorStrategy.Resume$	resume()	Java API: Returning this directive resumes message processing for the failed Actor
SupervisorStrategy.Directive	resume(Logging.LogLevel logLevel)	Returning this directive resumes message processing for the failed Actor.
scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive>	seqThrowable2Decider(scala.collection.immutable.Seq<java.lang.Class<? extends java.lang.Throwable>> trapExit)	Implicit conversion from Seq of Throwables to a Decider.
SupervisorStrategy.Stop$	stop()	Java API: Returning this directive stops the Actor
SupervisorStrategy.Directive	stop(Logging.LogLevel logLevel)	Returning this directive stops the Actor
SupervisorStrategy	stoppingStrategy()	This strategy resembles Erlang in that failing children are always terminated (one-for-one).

Field Detail

MODULE$

public static final SupervisorStrategy$ MODULE$

Static reference to the singleton instance of this Scala object.

Constructor Detail

SupervisorStrategy$

public SupervisorStrategy$()

Method Detail

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<java.lang.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<java.lang.Throwable,SupervisorStrategy.Directive> seqThrowable2Decider(scala.collection.immutable.Seq<java.lang.Class<? extends java.lang.Throwable>> trapExit)

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

makeDecider

public scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive> makeDecider(scala.collection.immutable.Seq<java.lang.Class<? extends java.lang.Throwable>> trapExit)

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

makeDecider

public scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive> makeDecider(java.lang.Iterable<java.lang.Class<? extends java.lang.Throwable>> trapExit)

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

makeDecider

public scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive> makeDecider(scala.collection.Iterable<scala.Tuple2<java.lang.Class<? extends java.lang.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<java.lang.Throwable,SupervisorStrategy.Directive> makeDecider(Function<java.lang.Throwable,SupervisorStrategy.Directive> func)

Converts a Java Decider into a Scala Decider
