final class Transformation extends AnyRef

Transformation of events to the external (public) representation. Events can be excluded by mapping them to Optional.empty.

Not for direct construction, use Transformation.empty as starting point and register mappers to build your needed Transformation

  14. def registerAsyncEnvelopeMapper[A, B](inputEventClass: Class[A], f: Function[EventEnvelope[A], CompletionStage[Optional[B]]]): Transformation

    f

    A function that is fed each event envelope for payloads of type A and returns an async payload to emit, or Optional.empty() to filter the event from being produced.

  15. def registerAsyncEnvelopeOrElseMapper(f: Function[EventEnvelope[Any], CompletionStage[Optional[Any]]]): Transformation

    f

    A function that is fed each event envelope, that did not match any other registered mappers, returns an async payload to emit, or Optional.empty() to filter the event from being produced. Replaces any previous "orElse" mapper defined.

  16. def registerAsyncMapper[A, B](inputEventClass: Class[A], f: Function[A, CompletionStage[Optional[B]]]): Transformation

    f

    A function that is fed each event payload of type A and returns an async payload to emit, or Optional.empty() to filter the event from being produced.

  17. def registerAsyncOrElseMapper(f: (AnyRef) => CompletionStage[Optional[AnyRef]]): Transformation

    f

    A function that is fed each event payload, that did not match any other registered mappers, returns an async payload to emit, or Optional.empty() to filter the event from being produced. Replaces any previous "orElse" mapper defined.

  18. def registerEnvelopeMapper[A, B](inputEventClass: Class[A], f: Function[EventEnvelope[A], Optional[B]]): Transformation

    f

    A function that is fed each event envelope for payloads of type A and returns a payload to emit, or Optional.empty() to filter the event from being produced.

  19. def registerMapper[A, B](inputEventClass: Class[A], f: Function[A, Optional[B]]): Transformation

    f

    A function that is fed each event payload of type A and returns a payload to emit, or Optional.empty() to filter the event from being produced.

  20. def registerOrElseMapper(f: (AnyRef) => Optional[AnyRef]): Transformation

    f

    A function that is fed each event payload, that did not match any other registered mappers, returns a payload to emit, or Optional.empty() to filter the event from being produced. Replaces any previous "orElse" mapper defined.
