Method Summary

All Methods Instance Methods Concrete Methods
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$`	`escalate()`	Java API: Returning this directive escalates the failure to the supervisor of the supervisor, by rethrowing the cause of the failure, i.e.
`scala.Function1<java.lang.Object,SupervisorStrategy.Escalate$>`	`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.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.
`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()`
`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)`

  - resume

public SupervisorStrategy.Resume$ resume()

  - 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
```

```
    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:
    
    func - (undocumented)
    
    Returns:
    
    (undocumented)
  - sort
```
public 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).
