ClassDescriptionAbstractColumnAggregatorNode<Domain,
Accumulator, AggregateResult> Groups incoming tuples by the given mask, and aggregates values at a specific index in each group.ColumnAggregatorNode<Domain,Accumulator, AggregateResult> Timeless implementation of the column aggregator node.An aggregation node that simply counts the number of tuples conforming to the signature.GroupedMap<GroupedKeyType,ValueType> An optimizedMapimplementation where each key is produced by joining together a group tuple and some other object (via left inheritance).GroupedSet<GroupingValueType,GroupedKeyType, WholeKeyType> An optimizedSetimplementation where each contained value is produced by combining together a grouping value and some other (key) object.Expresses that aggregators expose specialized non-enumerable indexers for outer joining.A special node depending on a projection indexer to aggregate tuple groups with the same projection.
