Description

Prerequisite

Etymology

From "MeasurementSet" and "selection".

Synopsis

The MSSelection class represents a selection on a MeasurementSet (MS). This class is used in translating MS selections represented as selection items in the user interface, and for converting between MS selection and pure TaQL selection.

Example


 


 
Motivation

 This class is used by the MS access classes.
