Prerequisite

Synopsis

Global functions are needed to define the input of the flex scanner and to start the bison parser. The input is taken from a string.

Motivation

It is necessary to be able to give a table select 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.

To Do

Member Description

int tableGramParseCommand (const String& command)

Declare the bison parser (is implemented by bison command).

void TableGramerror (char*)

The yyerror function for the parser. It throws an exception with the current token.

Int& tableGramPosition()

Give the current position in the string. This can be used when parse errors occur.

int tableGramInput (char* buf, int max_size)

Declare the input routine for flex/bison.

String tableGramRemoveEscapes (const String& in)

A function to remove escaped characters.

String tableGramRemoveQuotes (const String& in)

A function to remove quotes from a quoted string.

MVTime tableGramParseDateTime (const String& in)

A function to parse a date/time string.

Double tableGramParseTime (const String& in)

A function to parse a time/position string. The value is returned in radians.
