Public Member Functions inherited from casacore::TableExprGroupFuncBase
	TableExprGroupFuncBase (TableExprNodeRep *node)
	Construct from the TaQL aggregation node.
virtual	~TableExprGroupFuncBase ()
	TableExprGroupFuncBase (const TableExprGroupFuncBase &)=delete
	Copying is not needed, thus not allowed.

virtual Bool	isLazy () const
	Does the aggregate function use lazy semantics? The default implementation returns False.

	Get the function's sequence nr.
void	setSeqnr (uInt seqnr)
	Set the function's sequence nr.
virtual void	apply (const TableExprId &id)=0
	Get the operand's value for the given row and apply it to the aggregation.
virtual void	finish ()
	If needed, finish the aggregation.
virtual std::shared_ptr< vector< TableExprId > >	getIds () const
	Get the assembled TableExprIds of a group.
