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.

Definition at line 273 of file TableParse.h.

◆ TableParseUpdate() [2/4]

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.

◆ TableParseUpdate() [3/4]

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.

◆ TableParseUpdate() [4/4]

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.
