Description copied from class: Aggregate

Creates a copy of this aggregate.

Specified by:

copy in class Aggregate

Parameters:

traitSet - Traits

input - Input

indicator - Whether row type should include indicator fields to indicate which grouping set is active; must be true if aggregate is not simple

groupSet - Bit set of grouping fields

groupSets - List of all grouping sets; null for just groupSet

aggCalls - Collection of calls to aggregate functions

Returns:

New Aggregate if any parameter differs from the value of this Aggregate, or just this if all the parameters are the same
