  3. def props(childProps: Props, childName: String, minBackoff: Duration, maxBackoff: Duration, randomFactor: Double, maxNrOfRetries: Int): Props

    Props for creating a BackoffSupervisor actor.

    Props for creating a BackoffSupervisor actor.

    Exceptions in the child are handled with the default supervision strategy, i.e. most exceptions will immediately restart the child. You can define another supervision strategy by using #propsWithSupervisorStrategy.

    childProps

    the akka.actor.Props of the child actor that will be started and supervised

    childName

    name of the child actor

    minBackoff

    minimum (initial) duration until the child actor will started again, if it is terminated

    maxBackoff

    the exponential back-off is capped to this duration

    randomFactor

    after calculation of the exponential back-off an additional random delay based on this factor is added, e.g. 0.2 adds up to 20% delay. In order to skip this additional delay pass in 0.

    maxNrOfRetries

    maximum number of attempts to restart the child actor. The supervisor will terminate itself after the maxNoOfRetries is reached. In order to restart infinitely pass in -1.

    Props for creating a BackoffSupervisor actor with a custom supervision strategy.

    Exceptions in the child are handled with the given supervisionStrategy. A Restart will perform a normal immediate restart of the child. A Stop will stop the child, but it will be started again after the back-off duration.

    childProps

    the akka.actor.Props of the child actor that will be started and supervised

    childName

    name of the child actor

    strategy
