TIfOperation.UpdateAggregate procedure
Update aggregate calculations for if operation
Declaration
procedure UpdateAggregate; overrideDescription

else-branch expressions of the conditional operation. It delegates the aggregate updates to all three operands.
The method is called repeatedly during aggregate processing to update the state of any aggregate functions contained within the conditional expressions.
