Constructor & Destructor Documentation

Scanner()

SlamParser::Scanner::Scanner	(	std::istream *	arg_yyin = 0,
		std::ostream *	arg_yyout = 0
	)

Create a new scanner object. The streams arg_yyin and arg_yyout default to cin and cout, but that assignment is only made when initializing in yylex().

Member Function Documentation

lex()

virtual Parser::token_type SlamParser::Scanner::lex ( Parser::semantic_type *  yylval, Parser::location_type *  yylloc  )

virtual

This is the main lexing function. It is generated by flex according to the macro declaration YY_DECL above. The generated bison parser then calls this virtual function to fetch new tokens.

set_debug()

void SlamParser::Scanner::set_debug

(

bool

b

)

Enable debug output (via arg_yyout) if compiled into the scanner.
