Synopsis

TableParseUpdate holds the column name, optional indices, optional mask, and new value expression of a column to be updated. Furthermore, it has functions to perform updates in the column and possibly mask column using the expression and possible slice.

Constructor & Destructor Documentation

◆ TableParseUpdate() [1/4]

casacore::TableParseUpdate::TableParseUpdate ( )

inline

Definition at line 65 of file TableParseUpdate.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.
