Class RestartSource$

  • public class RestartSource$
extends java.lang.Object
    Wrap the given Source with a Source that will restart it when it fails or complete using an exponential backoff.

    This Source will never emit a complete or failure, since the completion or failure of the wrapped Source is always handled by restarting it. The wrapped Source can however be cancelled by cancelling this Source. When that happens, the wrapped Source, if currently running will be cancelled, and it will not be restarted. This can be triggered simply by the downstream cancelling, or externally by introducing a KillSwitch right after this Source in the graph.

    This uses the same exponential backoff algorithm as Backoff.

    param: minBackoff minimum (initial) duration until the child actor will started again, if it is terminated param: maxBackoff the exponential back-off is capped to this duration param: 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. param: sourceFactory A factory for producing the Source to wrap.

        Wrap the given Source with a Source that will restart it when it fails or complete using an exponential backoff.

        This Source will not emit a complete or failure as long as maxRestarts is not reached, since the completion or failure of the wrapped Source is handled by restarting it. The wrapped Source can however be cancelled by cancelling this Source. When that happens, the wrapped Source, if currently running will be cancelled, and it will not be restarted.
