    • isCompatible

      public boolean isCompatible(CalcResult targetResults)
      Description copied from interface: CalcResult
      Returns true if the target results is a compatible type with the current results, with compatible meaning that the two results may be merged.
      Specified by:
      isCompatible in interface CalcResult
      Parameters:
      targetResults - the second CalcResult Object
      Returns:
      true if the targetResults can be merged with the current results

    • merge

      public CalcResult merge(CalcResult resultsToAdd)
      Description copied from interface: CalcResult
      Returns the merged results of two CalcResult. The way in which the results are merged is dependent on the type of the results added. A new instance is created containing the merged results.

      For example: merging two min functions would return the smaller of the two values; merging a count and a sum would return an average.

      Specified by:
      merge in interface CalcResult
      Returns:
      the merged results
