Detailed Description

An implementation class for the MeasurementSet to share code.

Intended use:

Internal

Review Status

Reviewed By:

Bob Garwood

Date Reviewed:

1997/02/01

Prerequisite

• MeasurementSet

Etymology

The MSTableImpl implements non-templated static functions shared by all MSTable objects.

Synopsis

MSTableImpl is only for internal use by the MeasurementSet base class MSTable.

Example

Motivation

The reasons for existance for this class are: sharing of code between the various MeasurementSet Tables and avoiding duplicate code in the instantiations of MSTable

Member Function Documentation

static void casa::MSTableImpl::addColumnCompression	(	TableDesc &	,
		const String &	colName,
		Bool	autoScale,
		const String &	type
	)		[static]

Add the compress option for the given column to the TableDesc.

static void casa::MSTableImpl::addColumnToDesc	(	TableDesc &	td,
		const String &	colName,
		Int	colDType,
		const String &	colComment,
		const String &	colUnit,
		const String &	colMeasure,
		Int	ndim,
		const IPosition &	shape,
		Int	option,
		const String &	refCol
	)		[static]

add a column to a TableDesc An exception is thrown for an invalid data type.

This indicates a programming error in this class when this occurs. If option!=0 shape is used to set the shape of the column and option defines the type of column (ColumnDesc::Fixed/Direct). If option==0, shape is ignored and ndim is used to specify the array dimension if any. If refCol is not empty, a column with variable reference will be created, note that refCol should already exist in td.

Thrown Exceptions

• AipsError

static void casa::MSTableImpl::addKeyToDesc	(	TableDesc &	td,
		const String &	keyName,
		Int	keyDType,
		const String &	keyComment
	)		[static]

add a keyword to a TableDesc An exception is thrown for an invalid data type.

This indicates a missing data type in the code..

		Int	col,
		const String &	colName,
		Int	colType,
		const String &	colComment,

static Table casa::MSTableImpl::referenceCopy	(	const Table &	tab,
		const String &	newTableName,
		const Block< String > &	writableColumns

static Bool casa::MSTableImpl::validate	(	const TableRecord &	tabRec,
		const TableDesc &	requiredTD
	)		[static]
