Prerequisite

Etymology

ROMSHistoryColumns stands for Read-Only MeasurementSet History Table columns.

Synopsis

This class provides read-only access to the columns in the MSHistory 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 ROMSColumns for an example.

Motivation

See MSColumns for the motivation.
