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.

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.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
ClassicTokenizerImpl ( TextReader.TextReader @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.

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
ZzUnpackRowMap ( ) : int[]
ZzUnpackTrans ( string packed, int offset, int result ) : int
ZzUnpackTrans ( ) : 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

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.TextReader reader ) : void
reader System.IO.TextReader.TextReader the new input stream
return void
