```
private static char[] zzUnpackCMap(java.lang.String packed)
```
    Unpacks the compressed character translation table.
    
    Parameters:
    
    packed - the packed character translation table
    
    Returns:
    
    the unpacked character translation table
  - zzRefill
```
private boolean zzRefill()
                  throws java.io.IOException
```
    Refills the input buffer.
    
    Returns:
    
    false, iff there was new input.
    
    Throws:
    
    java.io.IOException - if any I/O-Error occurs
  - yyclose
```
public final void yyclose()
                   throws java.io.IOException
```
    Closes the input stream.
    
    Throws:
    
    java.io.IOException
  - yyreset
```
public final void yyreset(java.io.Reader reader)
```
    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.
    
    Parameters:
    
    reader - the new input stream
  - yystate
```
public final int yystate()
```
    Returns the current lexical state.
  - yybegin
```
public final void yybegin(int newState)
```
    Enters a new lexical state
    
    Parameters:
    
    newState - the new lexical state
  - yytext
```
public final java.lang.String yytext()
```
    Returns the text matched by the current regular expression.
  - yycharat
```
public final char yycharat(int pos)
```
    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()
```
    Returns the length of the matched text region.
  - zzScanError
```
private void zzScanError(int errorCode)
```
    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
  - yypushback
```
public void yypushback(int number)
```
    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()!
  - zzDoEOF
```
private void zzDoEOF()
              throws java.io.IOException
```
    Contains user EOF-code, which will be executed exactly once, when the end of file is reached
    
    Throws:
    
    java.io.IOException
  - yylex
```
public int yylex()
          throws java.io.IOException
```
    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
