selectExprProcessor
- - for processing the select expression and generting the final output rowsgroupKeyNodes
- - list of group-by expression nodes needed for building the group-by keysoptionalHavingNode
- - expression node representing validated HAVING clause, or null if none given.
Aggregation functions in the having node must have been pointed to the AggregationService for evaluation.isSelectRStream
- - true if remove stream events should be generatedisUnidirectional
- - true if unidirectional joinpublic ResultSetProcessor instantiate(OrderByProcessor orderByProcessor, AggregationService aggregationService, AgentInstanceContext agentInstanceContext)
