Detailed Description

Scanner for converting Mealmaster recipes to XML. This class converts the contents of the input to XML and writes it to the output-stream.

At any time there must only be one instance of this class.

See description of Mealmaster file-format for more information.

Constructor & Destructor Documentation

MealMasterCompiler::MealMasterCompiler	(	int	_maxRecipes = -1,
		MealMasterParseErrorHandlerPtr	_parseErrorHandler = MealMasterParseErrorHandlerPtr( new MealMasterParseErrorHandler )
	)

Constructor. It is possible to limit the number of recipes, which will be parsed by a call of translate. This is necessary, if this compiler is used in a chain with a XSL translator, which will store all data in memory before processing it.

Parameters:

	_maxRecipes	Maximum recipes to parse. Abort afterwards.
	_parseErrorHandler	Error handler for parse errors.

Member Function Documentation

virtual void MealMasterCompiler::translate	(	std::istream &	inputStream,
		std::ostream &	outputStream
	)			const throw (Error) [virtual]

Translate recipes. If the number of recipes, to be read, was limited by specifying _maxRecipes with the constructor, the stream will be repositioned (because flex usually will have read ahead, to fill its buffer).

The lexer keeps track of its read-position. This was implemented using the YY_USER_ACTION macro of flex. Note that the input-position will also change, when yymore(), yyless(), unput(), input() or REJECT are executed.

If no maximum number of recipes was specified in the constructor, the inputStream will be parsed up to its end.

Parameters:

	inputStream	Input stream to read mealmaster data from.
	outputStream	Output stream to write XML data to.

Implements Compiler.
