Detailed Description

A class to provide easy access to MeasurementSet columns

Intended use:

Public interface

Review Status

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

Prerequisite

Etymology

MSColumns stands for MeasurementSet Table columns.

Synopsis

This class provides access to all the subtables and direct access to all the columns in the MeasurementSet. 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.

Example

// use as follows
MeasurementSet ms("myMS",Table::Update); 
MSColumns msc(ms);
// show data from row 5
cout << msc.data()(5);
// change name of antenna on row 3 in antenna table
msc.antenna().name().put(3,"NewAnt-3");

Motivation

Having to type long lists of Scalar and Array column declarations gets very tedious. This class attempts to relieve some of that tedium, while at the same time concentrating all the declarations in one place, making Type errors in the column declaration (only caught at run-time) less probable. Type errors in the use of the columns is caught at compile time.

To Do

We might decide to merge this class with the MeasurementSet

set the EPOCH reference type in all EPOCH columns in the MS.

Note that only a single EPOCH reference is allowed in the MS. This
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;
