    • Method Detail

      • pairTo

        void pairTo​(T instance)
     throws ASGRuntimeException
        Pairs this instance to another service. The paired instanceof the service shouldn't be used directly anymore (until unpaired). Pairing is useful if you want to perform bulk write operations and let them be written back to the original service. Pairing will force all current data to be thrown away.
        Parameters:
        instance - a T object.
        Throws:
        ASGRuntimeException - if any.

      • unpair

        void unpair​(T instance)
     throws ASGRuntimeException
        Unpairs the service. Only previously paired service can be unpaired.
        Parameters:
        instance - a T object.
        Throws:
        ASGRuntimeException - if any.

      • readFrom

        void readFrom​(T anInstance)
       throws ASGRuntimeException
        Reads the data from a given instance. Only possible if unpaired.
        Parameters:
        anInstance - a T object.
        Throws:
        ASGRuntimeException - if any.

      • synchTo

        void synchTo​(T anInstance)
      throws ASGRuntimeException
        Synches current data to a service instance. The results are quite unpredictable.
        Parameters:
        anInstance - a T object.
        Throws:
        ASGRuntimeException - if any.
