Detailed Description

A class for easy read-only access to MeasurementSet main table columns.

Intended use:

Public interface

Review Status

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

Prerequisite

Etymology

ROMSColumns stands for Read-Only MeasurementSet Table columns.

Synopsis

This class provides read-only access to 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.
Warning: The Table that is used to construct this class must not be destroyed (or go out of scope) before this class does; Otherwise the scalar and array columns use by this class will be left dangling;

Example

    // use as follows
    MeasurementSet ms("myMS"); 
    ROMSColumns msc(ms);
    // show data from row 5
    cout << msc.data()(5);
    // show name of antenna on row 3 in antenna table
    cout << msc.antenna().name();

Motivation

See MSColumns for the motivation.

To Do

We might decide to merge all the MSColumn classes with the corresponding MeasurementSet classes.
