Detailed Description

A class to provide easy read-only access to MeasurementSet columns.

Intended use:

Public interface

Review Status

Prerequisite

• MeasurementSet
• ArrayColumn
• ScalarColumn

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.

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.
