Public Methods

Method	Description
GetNextToken ( ) : int	Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.
GetText ( ICharTermAttribute t ) : void	Fills CharTermAttribute with the current token text.
StandardTokenizerImpl ( TextReader @in ) : Lucene.Net.Analysis.Tokenattributes	Creates a new scanner
YyBegin ( int newState ) : void	Enters a new lexical state
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.
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 ( TextReader 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.

Private Methods

Method	Description
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.
ZzUnpackAction ( string packed, int offset, int result ) : int
ZzUnpackAction ( ) : int[]
ZzUnpackAttribute ( string packed, int offset, int result ) : int
ZzUnpackAttribute ( ) : int[]
ZzUnpackCMap ( string packed ) : char[]	Unpacks the compressed character translation table.
ZzUnpackRowMap ( string packed, int offset, int result ) : int

Method Details

GetNextToken() public method

Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.

if any I/O-Error occurs

public GetNextToken ( ) : int
return	int

GetText() public method

Fills CharTermAttribute with the current token text.

public GetText ( ICharTermAttribute t ) : void
t	ICharTermAttribute
return	void

StandardTokenizerImpl() public method

Creates a new scanner

public StandardTokenizerImpl ( TextReader @in ) : Lucene.Net.Analysis.Tokenattributes
@in	TextReader
return	Lucene.Net.Analysis.Tokenattributes

YyBegin() public method

Enters a new lexical state

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

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

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 ( TextReader reader ) : void
reader	TextReader	the new input stream
return	void

HANGUL_TYPE public_oe static_oe property

public static int HANGUL_TYPE
return	int

HIRAGANA_TYPE public_oe static_oe property

public static int HIRAGANA_TYPE
return	int

IDEOGRAPHIC_TYPE public_oe static_oe property

public static int IDEOGRAPHIC_TYPE
return	int

KATAKANA_TYPE public_oe static_oe property

public static int KATAKANA_TYPE
return	int

NUMERIC_TYPE public_oe static_oe property

Numbers

public static int NUMERIC_TYPE
return	int

SOUTH_EAST_ASIAN_TYPE public_oe static_oe property

Chars in class \p{Line_Break = Complex_Context} are from South East Asian scripts (Thai, Lao, Myanmar, Khmer, etc.). Sequences of these are kept together as as a single token rather than broken up, because the logic required to break them at word boundaries is too complex for UAX#29.

See Unicode Line Breaking Algorithm: http://www.unicode.org/reports/tr14/#SA

public static int SOUTH_EAST_ASIAN_TYPE
return	int

WORD_TYPE public_oe static_oe property

Alphanumeric sequences

public static int WORD_TYPE
return	int

YYEOF public_oe static_oe property

This character denotes the end of file

public static int YYEOF
return	int
