Public Methods

Method	Description
getText ( CharTermAttribute t ) : void	Fills CharTermAttribute with the current token text.
yybegin ( int newState ) : void	Enters a new lexical state
yychar ( ) : int
yycharat ( int pos ) : char	Returns the character at position `pos` from the matched text. It is equivalent to yytext().charAt(pos), but faster
yyclose ( ) : void	Closes the input stream.
yylength ( ) : int	Returns the length of the matched text region.
yypushback ( int number ) : void	Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method
yyreset ( Reader reader ) : void	Resets the scanner to read from a new input stream. Does not close the old reader. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to `ZZ_INITIAL`. Internal scan buffer is resized down to its initial length, if it has grown.
yystate ( ) : int	Returns the current lexical state.
yytext ( ) : string	Returns the text matched by the current regular expression.

Private Methods

Method	Description
ClassicTokenizerImpl ( Reader @in ) : System	Creates a new scanner
zzRefill ( ) : bool	Refills the input buffer.
zzScanError ( int errorCode ) : void	Reports an error that occured while scanning. In a wellformed scanner (no or only correct usage of yypushback(int) and a match-all fallback rule) this method will only be called with things that "Can't Possibly Happen". If this method is called, something is seriously wrong (e.g. a JFlex bug producing a faulty scanner etc.). Usual syntax/scanner level error handling should be done in error fallback rules.

zzUnpackAttribute ( string packed, int offset, int result ) : int

zzUnpackCMap ( string packed ) : char[]	Unpacks the compressed character translation table.

Method Details

getText() public method

Fills CharTermAttribute with the current token text.

public getText ( CharTermAttribute t ) : void
t	CharTermAttribute
return	void

yybegin() public method

Enters a new lexical state

public yybegin ( int newState ) : void
newState	int	the new lexical state
return	void

yychar() public method

public yychar ( ) : int
return	int

yycharat() public method

Returns the character at position pos from the matched text. It is equivalent to yytext().charAt(pos), but faster

public yycharat ( int pos ) : char
pos	int	the position of the character to fetch. /// A value from 0 to yylength()-1. ///
return	char

yyclose() public method

Closes the input stream.

public yyclose ( ) : void
return	void

yylength() public method

Returns the length of the matched text region.

public yylength ( ) : int
return	int

yypushback() public method

Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method

public yypushback ( int number ) : void
number	int	the number of characters to be read again. /// This number must not be greater than yylength()!
return	void

yyreset() public method

Resets the scanner to read from a new input stream. Does not close the old reader. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to ZZ_INITIAL. Internal scan buffer is resized down to its initial length, if it has grown.

public yyreset ( Reader reader ) : void
reader	Reader	the new input stream
return	void

yystate() public method

Returns the current lexical state.

public yystate ( ) : int
return	int

yytext() public method

Returns the text matched by the current regular expression.

public yytext ( ) : string
return	string
