Field Summary
static SupervisorStrategy$ MODULE$
          Static reference to the singleton instance of this Scala object.
 
Constructor Summary
SupervisorStrategy$()
           
 
Method Summary
 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.Function1<java.lang.Object,SupervisorStrategy.Escalate$> escalateDefault()
           
 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(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(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.
 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.Option<java.lang.Object> maxNrOfRetriesOption(int maxNrOfRetries)
           
 SupervisorStrategy.Restart$ restart()
          Java API: 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
 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.
 scala.collection.immutable.Seq<scala.Tuple2<java.lang.Class<? extends java.lang.Throwable>,SupervisorStrategy.Directive>> sort(scala.collection.Iterable<scala.Tuple2<java.lang.Class<? extends java.lang.Throwable>,SupervisorStrategy.Directive>> in)
          Sort so that subtypes always precede their supertypes, but without obeying any order between unrelated subtypes (insert sort).
 SupervisorStrategy.Stop$ stop()
          Java API: Returning this directive stops the Actor
 SupervisorStrategy stoppingStrategy()
          This strategy resembles Erlang in that failing children are always terminated (one-for-one).
 scala.Option<scala.concurrent.duration.Duration> withinTimeRangeOption(scala.concurrent.duration.Duration withinTimeRange)

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

Returns:
(undocumented)

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.

Returns:
(undocumented)

stop

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

Returns:
(undocumented)

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.

Returns:
(undocumented)

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 ActorInitializationException, ActorKilledException, or DeathPactException is thrown. It will be restarted for other Exception types. The error is escalated if it's a Throwable, i.e. Error.

Returns:
(undocumented)

defaultStrategy

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

Returns:
(undocumented)

stoppingStrategy

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

Returns:
(undocumented)

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.

Parameters:
trapExit - (undocumented)
Returns:
(undocumented)

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.

Parameters:
trapExit - (undocumented)
Returns:
(undocumented)

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.

Parameters:
trapExit - (undocumented)
Returns:
(undocumented)

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.

Parameters:
flat - (undocumented)
Returns:
(undocumented)

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

Parameters:

Returns:
