public static GroupAggregator CreateInstance( IValueExtractor extractor, IEntryAggregator aggregator ) |
Parameters
- extractor

Return Value
An instance of GroupAggregator based on a specified extractor and an IEntryAggregator.Remarks

GroupAggregator will not be parallel-aware and could be
ill-suited for aggregations run against large partitioned caches.
