ClassDescriptionFactory for iterative absolute sum aggregations.Produces an AggregationContext for aggregations given a table and the names of the group by columns.Transformer to adjust aggregation results for operation building.Stateless "control" class for giving external code (e.g.Marker interface for AggregationStates to use for memoization keys.The aggregation state factory is passed to the by operation, and is used to create new aggregation states for each of the output rows (or in case of byExternal, each of the output tables).Enumeration representing valid aggregation types for
