	Selection collection to put parsed selections in.
std::exception_ptr	exception
	Stores an exception that occurred during parsing.
bool	bGroups
	Whether external index groups have been set.
struct gmx_ana_indexgrps_t *	grps
	External index groups for resolving group keywords.
int	nexpsel
	Number of selections at which the parser should stop.
gmx::TextWriter *	statusWriter
	Writer to use for status output (if not NULL, parser is interactive).
std::string	pselstr
	Pretty-printed version of the string parsed since last clear.
gmx::SelectionLocation	currentLocation
	Position of the result of the current Bison action. More...
struct gmx_ana_selmethod_t **	mstack
	Stack of methods in which parameters should be looked up.
int	msp
	Index of the top of the stack in mstack.
int	mstack_alloc
	Number of elements allocated for mstack.
int	neom
	Number of END_OF_METHOD tokens to return before nextparam.
struct gmx_ana_selparam_t *	nextparam
	Parameter symbol to return before resuming scanning.
bool	bBoolNo
	Whether nextparam was a boolean parameter with a 'no' prefix.
const gmx::SelectionParserSymbol *	nextMethodSymbol
	Method symbol to return before resuming scanning. More...
int	prev_pos_kw
	Used to track whether the previous token was a position modifier.
bool	bMatchOf
	Whether the 'of' keyword is acceptable as the next token.
bool	bMatchBool
	Whether boolean values (yes/no/on/off) are acceptable as the next token.
bool	bCmdStart
	Whether the next token starts a new selection.
bool	bBuffer
	Whether an external buffer is set for the scanner.
YY_BUFFER_STATE	buffer
	The current buffer for the scanner.

Member Data Documentation

gmx::SelectionLocation gmx_sel_lexer_t::currentLocation

Position of the result of the current Bison action.

This identifies the part of pselstr that corresponds to the subselection that is currently being reduced by Bison.

const gmx::SelectionParserSymbol* gmx_sel_lexer_t::nextMethodSymbol

Method symbol to return before resuming scanning.

Only used when nextparam is NULL.
