AkkaStreamletContext

trait AkkaStreamletContext extends StreamletContext

Runtime context for AkkaStreamlets, which provides means to create Sources and Sinks respectively for CodeInlets and CodeOutlets. The StreamletContext also contains some lifecycle hooks, like signalReady, onStop and stop and provides access to the streamlet configuration. It also provides the ActorSystem and Materializer that will be used to run the AkkaStreamlet.

Abstract Value Members

  1. abstract def alive(localMode: Boolean): Unit

    Marks the streamlet pod "alive" for Kubernetes.

  2. abstract def ready(localMode: Boolean): Unit

    Marks the streamlet pod "ready" for Kubernetes.

  3. abstract def signalReady(): Boolean

    Signals that the streamlet is ready to process data.

    Signals that the streamlet is ready to process data.

    When a streamlet is run using AkkaStreamletTestkit.run, a StreamletExecution is returned. signalReady completes the ready future. ready can be used for instance to wait for a Server to signal that it is ready to accept requests.

    returns

    true if and only if successfully signalled. Otherwise false.

  4. abstract def stop(): Future[Dun]

    Stops the streamlet.

  5. abstract def stopOnException(nonFatal: Throwable): Unit

    Stops the streamlet knowing an exception occured.

  6. implicit abstract def system: ActorSystem

    The system in which the AkkaStreamlet will be run.
