Detailed Description

The Driver class brings together all components. It creates an instance of the Parser and Scanner classes and connects them. Then the input stream is fed into the scanner object and the parser gets it's token sequence. Furthermore the driver object is available in the grammar rules as a parameter. Therefore the driver class contains a reference to the structure into which the parsed data is saved.

Constructor & Destructor Documentation

Driver()

DefParser::Driver::Driver

(

DefDataBase &

db

)

construct a new parser driver context

Parameters

db	reference to database

Member Function Documentation

parse_file()

bool DefParser::Driver::parse_file

(

const string &

filename

)

Invoke the scanner and parser on a file. Use parse_stream with a std::ifstream if detection of file reading errors is required.

Parameters

filename

input file name

Returns

true if successfully parsed

parse_stream()

bool DefParser::Driver::parse_stream	(	std::istream &	in,
		const string &	sname = "stream input" )

Invoke the scanner and parser for a stream.

Parameters

in	input stream
sname	stream name for error messages

Returns

true if successfully parsed

parse_string()

bool DefParser::Driver::parse_string	(	const string &	input,
		const string &	sname = "string stream" )

Invoke the scanner and parser on an input string.

Parameters

input	input string
sname	stream name for error messages

Returns

true if successfully parsed
