Creates a new scanner There is also a java.io.InputStream version of this constructor.

Parameters:

  public StrftimeLexer(java.io.Reader in) {
    this. = in;
  }

  
Creates a new scanner. There is also java.io.Reader version of this constructor.

Parameters:
in the java.io.Inputstream to read input from.
  public StrftimeLexer(java.io.InputStream in) {
    this(new java.io.InputStreamReader(in));
  }

  
Unpacks the compressed character translation table.

Parameters:
packed the packed character translation table
Returns:
the unpacked character translation table
  private static char [] zzUnpackCMap(String packed) {
    char [] map = new char[0x10000];
    int i = 0;  /* index in packed string  */

      do map[j++] = valuewhile (--count > 0);
    }
    return map;
  }


  
Refills the input buffer.

Returns:
false, iff there was new input.
Throws:
java.io.IOException if any I/O-Error occurs
  private boolean zzRefill() throws java.io.IOException {
    /* first: make room (if you can) */
    if ( > 0) {

      return true;
    }
    else {
      += numRead;
      return false;
    }
  }

    
  
Closes the input stream.
  public final void yyclose() throws java.io.IOException {
     = true;            /* indicate end of file */
     = ;  /* invalidate buffer    */
    if ( != null)
      .close();
  }


  
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
  public final void yyreset(java.io.Reader reader) {
     = reader;
      = true;
      = false;
     =  = 0;
     =  =  = 0;
  }


  
Returns the current lexical state.
  public final int yystate() {
    return ;
  }


  
Enters a new lexical state

Parameters:
newState the new lexical state
  public final void yybegin(int newState) {
     = newState;
  }


  
Returns the text matched by the current regular expression.
  public final String yytext() {
    return new String- );
  }


  
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
  public final char yycharat(int pos) {
    return [+pos];
  }


  
Returns the length of the matched text region.
  public final int yylength() {
    return -;
  }


  
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.

Parameters:
errorCode the code of the errormessage to display
  private void zzScanError(int errorCode) {
    String message;
    try {
      message = [errorCode];
    }
    catch (ArrayIndexOutOfBoundsException e) {
      message = [];
    }
    throw new Error(message);
  } 


  
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()!
  public void yypushback(int number)  {
    if ( number > yylength() )
     -= number;
  }


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

Returns:
the next token
Throws:
java.io.IOException if any I/O-Error occurs
