  • public interface SessionedJsonifiable
    Jsonifiable with information from the streaming session.

    • Method Detail

      • getJsonifiable

        org.eclipse.ditto.model.base.json.Jsonifiable.WithPredicate<org.eclipse.ditto.json.JsonObject,​org.eclipse.ditto.json.JsonField> getJsonifiable()
        Retrieve the Jsonifiable.
        Returns:
        the Jsonifiable.

      • getDittoHeaders

        org.eclipse.ditto.model.base.headers.DittoHeaders getDittoHeaders()
        Retrieve the Ditto headers of the Jsonifiable.
        Returns:
        the Ditto headers.

      • retrieveExtraFields

        CompletionStage<org.eclipse.ditto.json.JsonObject> retrieveExtraFields​(@Nullable
                                                                       SignalEnrichmentFacade facade)
        Retrieve extra fields for the Jsonifiable according to the session information. If the Jsonifiable does not support extra fields, then a future empty Json object is returned. If the Jsonifiable supports extra fields but retrieval is impossible, then a failed future is returned.
        Parameters:
        facade - the signal enrichment facade with which extra fields are retrieved.
        Returns:
        future of the result of retrieval.

      • getSession

        Optional<StreamingSession> getSession()
        Retrieve the streaming session if this is a signal and has an associated session.
        Returns:
        the session if any exists.

      • signal

                                   StreamingSession session)
        Create a sessioned Jsonifiable for a signal.
        Parameters:
        signal - the signal.
        sessionHeaders - headers of the request that created the streaming session.
        session - session information for the signal's streaming type.
        Returns:
        the sessioned Jsonifiable.
