the number of times a child actor is allowed to be restarted, negative value means no limit, if the limit is exceeded the child actor is stopped
duration of the time window for maxNrOfRetries, Duration.Inf means no window
the strategy logs the failure if this is enabled (true), by default it is enabled
mapping from Throwable to akka.actor.SupervisorStrategy.Directive, you can also use a scala.collection.immutable.Seq of Throwables which maps the given Throwables to restarts, otherwise escalates.

This method is called after the child has been removed from the set of children.
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.
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.

This method calls akka.actor.SupervisorStrategy#logFailure, which will
log the failure unless it is escalated. You can customize the logging by
setting akka.actor.SupervisorStrategy#loggingEnabled to false
and
do the logging inside the decider
or override the logFailure
method.

Escalate
failures are not logged here, since they are supposed
to be handled at a level higher up in the hierarchy.
Resume
failures are logged at Warning

failures are logged at Error

Restart the given child, possibly suspending it first.
Restart the given child, possibly suspending it first.
IMPORTANT:
If the child is the currently failing one, it will already have been
suspended, hence suspendFirst
must be false. If the child is not the
currently failing one, then it did not request this treatment and is
therefore not prepared to be resumed without prior suspend.
Resume the previously failed child: do never apply this to a child which is not the currently failing child.
Resume the previously failed child: do never apply this to a child which is not the currently failing child. Suspend/resume needs to be done in matching pairs, otherwise actors will wake up too soon or never at all.
