Detailed Description

Class to hold values from field grammar parser.

Intended use:



MSPolnParse is the class used to parse a polarization selection command.


MSPolnParse is used by the parser of polarization sub-expression statements of the type [SPW:]POLN. Since this is a relatively simple expression to tokenize and parse, this parser is written without Bison or Flex. The methods of this class take an expression, and internally generate a list of the Data Description IDs that should be used to select the rows in the MS main table. The map of Polarization IDs (row numbers in the POLARIZATION sub-table) and the list of indices to be used to pick the user selected polarzation data (in the DATA columns of the MS main table) is also generated. This map is intended to be used along with the map of SPW and selected channels to apply the in-row selection (Slice on the data columns).


It is necessary to be able to give a data selection command in ASCII. This can be used in a CLI or in the table browser to get a subset of a table or to sort a table.
