AbstractInteger64Aggregator Class Reference
Inherited by Integer64Max, Integer64Min, and Integer64Sum.
List of all members.
Abstract aggregator that processes numeric values extracted from a set of entries in a Map.
All the extracted Number objects will be treated as
int64_t values and the result of the aggregator is a Integer64. If the set of entries is empty, a
NULL result is returned.

Protected Member Functions
virtual void ||init (bool fFinal)|
| ||Initialize the aggregation result.|
|fFinal ||true is passed if the aggregation process that is being initialized must produce a final aggregation result; this will only be false if a parallel approach is being used and the initial (partial) aggregation process is being initialized|
virtual Object::Holder ||finalizeResult (bool fFinal)|
| ||Obtain the result of the aggregation.|
fFinal parameter is true, the returned object must be the final result of the aggregation; otherwise, the returned object will be treated as a partial result that should be incorporated into the final result.
|fFinal ||true to indicate that the final result of the aggregation process should be returned; this will only be false if a parallel approach is being used|
- the result of the aggregation process
| ||The count of processed entries. |
| ||The running result value. |
