Detailed Description

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

Intended use:

Public interface

Review Status

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

Prerequisite

Etymology

MSFeedColumns stands for MeasurementSet Feed Table columns.

Synopsis

This class provides access to the columns in the MSFeed 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.

Motivation

See MSColumns for the motivation.

void casa::MSFeedColumns::setDirectionRef ( MDirection::Types ref )

set the direction type for the BEAM_OFFSET column.

This can only be done when the table has no rows. Trying to do so at other times will throw an exception.

void casa::MSFeedColumns::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;

void casa::MSFeedColumns::setPositionRef ( MPosition::Types ref )

set the position type for the POSITION column.

This can only be done when the table has no rows. Trying to do so at other times will throw an exception.
