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

BookshelfParser::Driver::Driver

(

BookshelfDataBase &

db

)

construct a new parser driver context

Parameters

db	reference to database

Member Function Documentation

vector<string> const& BookshelfParser::Driver::bookshelfFiles ( ) const

Definition at line 155 of file BookshelfDriver.h.

void BookshelfParser::Driver::error	(	const class location &	l,
		const string &	m
	)

Error handling with associated line number. This can be modified to output the error e.g. to a dialog box.

void BookshelfParser::Driver::error

(

const string &

m

)

General error handling. This can be modified to output the error e.g. to a dialog box.

bool BookshelfParser::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

bool BookshelfParser::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

bool BookshelfParser::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

void BookshelfParser::Driver::setPlFlag

(

bool

flag

)

control m_plFlag

Parameters

flag	control flag

Member Data Documentation

class Scanner* BookshelfParser::Driver::lexer

Pointer to the current lexer instance, this is used to connect the parser to the scanner. It is used in the yylex macro.

Definition at line 89 of file BookshelfDriver.h.

BookshelfDataBase& BookshelfParser::Driver::m_db

Reference to the database filled during parsing of the expressions.
