Modifier and Type	Method	Description
scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive>	decider()
void	handleChildTerminated(ActorContext context, ActorRef child, scala.collection.Iterable<ActorRef> children)	This method is called after the child has been removed from the set of children.
boolean	handleFailure(ActorContext context, ActorRef child, java.lang.Throwable cause, ChildRestartStats stats, scala.collection.Iterable<ChildRestartStats> children)	This is the main entry point: in case of a child&rsquo;s failure, this method must try to handle the failure by resuming, restarting or stopping the child (and returning true), or it returns false to escalate the failure, which will lead to this actor re-throwing the exception which caused the failure.
void	processFailure(ActorContext context, boolean restart, ActorRef child, java.lang.Throwable cause, ChildRestartStats stats, scala.collection.Iterable<ChildRestartStats> children)	This method is called to act on the failure of a child: restart if the flag is true, stop otherwise.

Method Detail

decider

public scala.PartialFunction<java.lang.Throwable,SupervisorStrategy.Directive> decider()

Specified by:

decider in class SupervisorStrategy

handleChildTerminated

public void handleChildTerminated(ActorContext context,
                                  ActorRef child,
                                  scala.collection.Iterable<ActorRef> children)

Description copied from class: SupervisorStrategy

This method is called after the child has been removed from the set of children. It does not need to do anything special. Exceptions thrown from this method do NOT make the actor fail if this happens during termination.

Specified by:

handleChildTerminated in class SupervisorStrategy

Parameters:

context - (undocumented)

child - (undocumented)

children - (undocumented)

handleFailure

public boolean handleFailure(ActorContext context,
                             ActorRef child,
                             java.lang.Throwable cause,
                             ChildRestartStats stats,
                             scala.collection.Iterable<ChildRestartStats> children)

Description copied from class: SupervisorStrategy

This is the main entry point: in case of a child’s failure, this method must try to handle the failure by resuming, restarting or stopping the child (and returning true), or it returns false to escalate the failure, which will lead to this actor re-throwing the exception which caused the failure. The exception will not be wrapped.

This method calls SupervisorStrategy.logFailure(akka.actor.ActorContext, akka.actor.ActorRef, java.lang.Throwable, akka.actor.SupervisorStrategy.Directive), which will log the failure unless it is escalated. You can customize the logging by setting SupervisorStrategy.loggingEnabled() to false and do the logging inside the decider or override the logFailure method.

Overrides:

handleFailure in class SupervisorStrategy

Parameters:

context - (undocumented)

cause - (undocumented)

stats - (undocumented)

children - is a lazy collection (a view)

Returns:

(undocumented)

processFailure

public void processFailure(ActorContext context,
                           boolean restart,
                           ActorRef child,
                           java.lang.Throwable cause,
                           ChildRestartStats stats,
                           scala.collection.Iterable<ChildRestartStats> children)

Description copied from class: SupervisorStrategy

This method is called to act on the failure of a child: restart if the flag is true, stop otherwise.

Specified by:

processFailure in class SupervisorStrategy

Parameters:

context - (undocumented)

restart - (undocumented)

child - (undocumented)

cause - (undocumented)

stats - (undocumented)

children - (undocumented)

update

public void update(ActorRef child,
                   SupervisorStrategy supervisor)
