Prerequisite

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 


 


 
Motivation

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

Member Description


enum Field

 The fields in the MS for which selection and range operations are
 defined. Some of these directly correspond to columns in the table,
 others are derived quantities or columns in subtables.

static Field field(const String& keyword)



 convert a keyword string to the corresponding enum

static const String& keyword(Field field)



 convert an enum value to the corresponding keyword string

MSSelectionKeywords()

 This class is purely static, no instances are allowed.

MSSelectionKeywords(const MSSelectionKeywords& other)


MSSelectionKeywords& operator=(const MSSelectionKeywords& other)


static void initMap(SimpleOrderedMap<String,Int>*& fieldMap, Block<Int>*& reverseMap)



 initialization function for the string to enum mapping
