Detailed Description

Class to hold values from field grammar parser.

Intended use:



MSSpwParse is the class used to parse a spectral window selection command.


MSSpwParse is used by the parser of spectral window (Spw) sub-expression statements. The parser is written in Bison and Flex in files MSSpwGram.y and.l. The statements in there use the routines in this file to act upon a reduced rule. Since multiple tables can be given (with a shorthand), the table names are stored in a list. The variable names can be qualified by the table name and will be looked up in the appropriate table.

The class MSSpwParse only contains information about a table used in the table command. Global variables (like a list and a vector) are used in to hold further information.

Global functions are used to operate on the information. The main function is the global function msSpwCommand. It executes the given STaQL command and returns the resulting ms. This is, in fact, the only function to be used by a user.


It is necessary to be able to give a ms 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.
