Detailed Description

MSSelectionKeywords specifies selection keywords for the MeasurementSet

Intended use:

Public interface

Review Status

Date Reviewed:

yyyy/mm/dd

Prerequisite

• MeasurementSet
• MSSelector

Etymology

MSSelectionKeywords is a class that defines selection keywords

Synopsis

This class is used to specify selections on a MeasurementSet. It is a purely static class that just defines a mapping from Strings to Enums, and provides these for use by classes like MSSelector and MSRange

Example

Motivation

Selection keywords are needed for several classes, this class provides them to all, avoiding duplication in each class.

Thrown Exceptions

To Do

• add this feature
