Field Detail

### YYEOF

    public static final int YYEOF

  Deprecated.
  This character denotes the end of file

### YYINITIAL

    public static final int YYINITIAL

  Deprecated.

    Constant Field Values

### WORD_TYPE

    public static final int WORD_TYPE

  Deprecated.
  Alphanumeric sequences

  See Also:
    Constant Field Values

### NUMERIC_TYPE

    public static final int NUMERIC_TYPE

  Deprecated.
  Numbers

  See Also:
    Constant Field Values

### SOUTH_EAST_ASIAN_TYPE

    public static final int SOUTH_EAST_ASIAN_TYPE

  Deprecated.
  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.

Constructor Detail

### StandardTokenizerImpl31

    public StandardTokenizerImpl31(Reader in)

  Deprecated.
  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.

### StandardTokenizerImpl31

    public StandardTokenizerImpl31(InputStream in)

  Deprecated.
  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

### yychar

    public final int yychar()

  Deprecated.
  Description copied from interface: `StandardTokenizerInterface`
  Returns the current position.

  Specified by:
    `yychar` in interface `StandardTokenizerInterface`

### getText

    public final void getText(CharTermAttribute t)

  Deprecated.
  Fills CharTermAttribute with the current token text.

  Specified by:
    `getText` in interface `StandardTokenizerInterface`

### yyclose

    public final void yyclose()
                       throws IOException

  Deprecated.
  Closes the input stream.

  Throws:
    `IOException`

### yyreset

    public final void yyreset(Reader reader)

  Deprecated.
  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.

  Specified by:
    `yyreset` in interface `StandardTokenizerInterface`
  Parameters:
    `reader` - the new input stream

### yystate

    public final int yystate()

  Deprecated.
  Returns the current lexical state.

### yybegin

    public final void yybegin(int newState)

  Deprecated.
  Enters a new lexical state

  Parameters:
    `newState` - the new lexical state

### yytext

    public final String yytext()

  Deprecated.
  Returns the text matched by the current regular expression.

### yycharat

    public final char yycharat(int pos)

  Deprecated.
  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.
  Returns:
    the character at position pos

### yylength

    public final int yylength()

  Deprecated.
  Returns the length of the matched text region.

  Specified by:
    `yylength` in interface `StandardTokenizerInterface`

### yypushback

    public void yypushback(int number)

  Deprecated.
  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()!

### getNextToken

    public int getNextToken()
                     throws IOException

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

  Specified by:
    `getNextToken` in interface `StandardTokenizerInterface`
  Returns:
    the next token
  Throws:
    `IOException` - if any I/O-Error occurs
