Etymology

TableParseUpdate holds a column name, optional indices, optional mask, and an update expression.

Synopsis

A table command is parsed. An object of this class is used to hold the column name, optional indices, and value expression for the UPDATE command.

Constructor & Destructor Documentation

casacore::TableParseUpdate::TableParseUpdate ( )

inline

Definition at line 266 of file TableParse.h.

casacore::TableParseUpdate::TableParseUpdate	(	const String &	columnName,
		const String &	columnNameMask,
		const TableExprNode &	,
		Bool	checkAggr = True
	)

Construct from a column name and expression.

By default it checks if no aggregate functions are used.

casacore::TableParseUpdate::TableParseUpdate	(	const String &	columnName,
		const String &	columnNameMask,
		const TableExprNodeSet &	indices,
		const TableExprNode &	,
		const TaQLStyle &
	)

Construct from a column name, subscripts or mask, and expression.

It checks if no aggregate functions are used.

casacore::TableParseUpdate::TableParseUpdate	(	const String &	columnName,
		const String &	columnNameMask,
		const TableExprNodeSet &	indices1,
		const TableExprNodeSet &	indices2,
		const TableExprNode &	,
		const TaQLStyle &
	)

Construct from a column name, subscripts and mask, and expression.

It checks if no aggregate functions are used. It checks if one of the indices represents subscripts, the other a mask.
