Decideris used by default in the supervisor strategy. The child will be stopped when akka.actor.ActorInitializationException, akka.actor.ActorKilledException, or akka.actor.DeathPactException is thrown. It will be restarted for otherExceptiontypes. The error is escalated if it's aThrowable, i.e.Error. - final val defaultStrategy: SupervisorStrategy

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.
- def makeDecider(trapExit: Iterable[Class[_ <: Throwable]]): Decider
Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.
- def makeDecider(trapExit: Seq[Class[_ <: Throwable]]): Decider
Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.
