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.

It throws an exception with the current token.

int casacore::TableGram_global_functions_TableGramFunctions::tableGramInput	(	char *	buf,
		int	max_size
	)

Declare the input routine for flex/bison.

int casacore::TableGram_global_functions_TableGramFunctions::tableGramParseCommand ( const String & command )

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

The value is returned in radians.

Int& casacore::TableGram_global_functions_TableGramFunctions::tableGramPosition ( )

Give the current position in the string.

This can be used when parse errors occur.
