isCompatible
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 interfaceCalcResult
- Parameters:
targetResults
- the second CalcResult Object- Returns:
- true if the targetResults can be merged with the current results
-
merge
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 interfaceCalcResult
- Returns:
- the merged results
