Detailed Description

A class to provide easy read-only access to new CalTable columns.

Intended use:

Public interface

Prerequisite

Etymology

ROCTColumns stands for Read-Only NewCalTable Table columns.

Synopsis

This class provides read-only access to the columns in the NewCalTable, similar to the ROMSColumns for 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
    NewCalTable newcalt("mynewcalt");
    RONCTColumns nctc(newcalt);
    // show time from row 5
    cout << nctc.time()(5);
    // show name of antenna on row 3 in antenna table
    cout << nctc.antenna().name();

Motivation
