Detailed Description

A class to provide easy read-write access to MSHistory columns.

Intended use:

Public interface

Review Status

Reviewed By:: Bob Garwood
Date Reviewed:: 1997/02/01

Prerequisite

Etymology

MSHistoryColumns stands for MeasurementSet History Table columns.

Synopsis

This class provides access to the columns in the MSHistory Table, it does the declaration of all the Scalar and ArrayColumns with the correct types, so the application programmer doesn't have to worry about getting those right. There is an access function for every predefined column. Access to non-predefined columns will still have to be done with explicit declarations. See MSColumns for an example.

Note by GvD 28-Jan-2010: According to note 229 the OBJECTID column should contain Strings. It is, however, defined as Int. It has to be left as such, otherwise older MeasurementSets cannot be read anymore.

Motivation

See MSColumns for the motivation.

void casa::MSHistoryColumns::setEpochRef	(	MEpoch::Types	ref,
		Bool	tableMustBeEmpty = `True`
	)

set the epoch type for the TIME column.

Tip: In principle this function can only be used if the table is empty, otherwise already written values may thereafter have an incorrect reference, offset, or unit; However, it is possible that part of the table gets written before these values are known; In that case the reference, offset, or units can be set by using a False tableMustBeEmpty argument;
