MSSelectionKeywords specifies selection keywords for the MeasurementSet.
Public interface
MSSelectionKeywords is a class that defines selection keywords
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
Selection keywords are needed for several classes, this class provides them to all, avoiding duplication in each class.
Definition at line 88 of file MSSelectionKeywords.h.
