      Returns:
        the result of aggregation
      Throws:
        `java.lang.Exception` - if the supplied object can't be aggregated for some reason

    - #### finalizeAggregation

          void finalizeAggregation()
                                   throws java.lang.Exception

      Call to complete the aggregation process. Allows implementers to do any final processing based on how many objects were aggregated.
