StandardTokenizerImpl(java.io.Reader in)(Code)
Creates a new scanner There is also a java.io.InputStream version of this constructor.
Parameters:
  in - the java.io.Reader to read input from.



StandardTokenizerImpl
StandardTokenizerImpl(java.io.InputStream in)(Code)
Creates a new scanner. There is also java.io.Reader version of this constructor.
Parameters:
  in - the java.io.Inputstream to read input from.




Method Detail
getNextToken
public int getNextToken() throws java.io.IOException(Code)
Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs. the next token
exception:
  java.io.IOException - if any I/O-Error occurs



getText
final void getText(Token t)(Code)
Fills Lucene token with the current token text.



yybegin
final public void yybegin(int newState)(Code)
Enters a new lexical state
Parameters:
  newState - the new lexical state



yychar
final public int yychar()(Code)



yycharat
final public char yycharat(int pos)(Code)
Returns the character at position pos from the matched text. It is equivalent to yytext().charAt(pos), but faster
Parameters:
  pos - the position of the character to fetch. A value from 0 to yylength()-1. the character at position pos



yyclose
final public void yyclose() throws java.io.IOException(Code)
Closes the input stream.



yylength
final public int yylength()(Code)
Returns the length of the matched text region.



yypushback
public void yypushback(int number)(Code)
Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method
Parameters:
  number - the number of characters to be read again.This number must not be greater than yylength()!



yyreset
final public void yyreset(java.io.Reader reader)(Code)
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.
Parameters:
  reader - the new input stream



yystate
final public int yystate()(Code)
Returns the current lexical state.



yytext
final public String yytext()(Code)
Returns the text matched by the current regular expression.
