		struct gmx_ana_selcollection_t *	sc,
		gmx::TextWriter *	statusWriter,
		int	maxnr,
		bool	bGroups,
		struct gmx_ana_indexgrps_t *	grps
	)

Initializes the selection scanner.

void _gmx_sel_lexer_add_token	(	::gmx::SelectionLocation *	,
		const char *	str,

Returns writer for status output (if not NULL, the scanner is interactive).

bool _gmx_sel_lexer_has_groups_set ( yyscan_t scanner )

Returns true if the external index groups for the scanner are set.

struct gmx_ana_indexgrps_t* _gmx_sel_lexer_indexgrps ( yyscan_t scanner )

int _gmx_sel_lexer_process_pending	(	YYSTYPE *	,
		::gmx::SelectionLocation *	,
		gmx_sel_lexer_t *	state
	)

Internal function for cases where several tokens need to be returned.

const char* _gmx_sel_lexer_pselstr ( yyscan_t scanner )

struct gmx_ana_selcollection_t* _gmx_sel_lexer_selcollection ( yyscan_t scanner )

Returns the selection collection for the scanner.

void _gmx_sel_lexer_set_current_location	(	yyscan_t	scanner,
		const gmx::SelectionLocation &	location
	)

Sets the current parser context location.

This location is set while Bison reductions are being processed, and identifies the location of the current rule/reduction.

void _gmx_sel_lexer_set_exception	(	yyscan_t	scanner,
		const std::exception_ptr &	ex
	)

Stores an exception that is caught during parsing.

void _gmx_sel_set_lex_input_file	(	yyscan_t	scanner,
		FILE *	fp
	)
