Detailed Description

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

Intended use:

Public interface

Review Status

Reviewed By:: Bob Garwood

Prerequisite

Etymology

MSFieldColumns stands for MeasurementSet Field Table columns.

Synopsis

This class provides access to the columns in the MSField 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.

casa::MSFieldColumns::MSFieldColumns ( MSField & msField )

Construct from the supplied Table.

Member Function Documentation

void casa::MSFieldColumns::attach ( MSField & msField ) [protected]

void casa::MSFieldColumns::attachOptionalCols ( MSField & msField ) [private]

ScalarColumn<String>& casa::MSFieldColumns::code ( ) [inline]

Read-write access to required columns.

Note that the direction measures with a stored polynomial have Col() added to their name. They are better accessed via the functions that have the same name, without the Col suffix, that will do the interpolation for you. These functions are in the ROMSFieldColumns class.

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

set the direction reference type for the REFERENCE_DIR, DELAY_DIR & PHASE_DIR columns.

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

void casa::MSFieldColumns::setEpochRef	(	MEpoch::Types	ref,
		Bool	tableMustBeEmpty = `True`
	)

set the epoch reference 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;
