Method Detail

finish

public void finish(VectorAggregateExpression.AggregationBuffer myagg,
                   boolean aborted)

Description copied from class: VectorAggregateExpression

Optional method to implement in VectorAggregateExpression instances. It's called for all aggregators from ProcessingMode, when VectorGroupByOperator is closed (before flush) or a write/flush happens. Calling this method properly before writing rows is the responsibility of VectorGroupByOperator.

Overrides:

finish in class VectorAggregateExpression
