    Description copied from class: CharFilter
    
    Closes the underlying input stream.
    NOTE: The default implementation closes the input Reader, so be sure to call super.close() when overriding this method.

    close in interface java.lang.AutoCloseable

  - getInitialBufferSize
```
static int getInitialBufferSize()
```
  - zzCMap
```
private static int zzCMap(int input)
```
    Translates raw input code points to DFA table row
  - 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
```
private final void yyclose()
                    throws java.io.IOException
```
    Closes the input reader.
    
    Throws:
    
    java.io.IOException - if the reader could not be closed.
  - yyreset
```
private 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.
  - yyResetPosition
```
private final void yyResetPosition()
```
    Resets the input position.
  - yyatEOF
```
private final boolean yyatEOF()
```
    Returns whether the scanner has reached the end of the reader it reads from.
    
    Returns:
    
    whether the scanner has reached EOF.
  - yystate
```
private final int yystate()
```
    Returns the current lexical state.
    
    Returns:
    
    the current lexical state.
  - yybegin
```
private final void yybegin(int newState)
```
    Enters a new lexical state.
    
    Parameters:
    
    newState - the new lexical state
  - yytext
```
private final java.lang.String yytext()
```
    Returns the text matched by the current regular expression.
    
    Returns:
    
    the matched text.
  - yycharat
```
private final char yycharat(int position)
```
    Returns the character at the given position from the matched text.
    It is equivalent to yytext().charAt(pos), but faster.
    
    Parameters:
    
    position - the position of the character to fetch. A value from 0 to yylength()-1.
    
    Returns:
    
    the character at position.
  - yylength
```
private final int yylength()
```
    How many characters were matched.
    
    Returns:
    
    the length of the matched text region.
  - zzScanError
```
private static void zzScanError(int errorCode)
```
    Reports an error that occurred while scanning.
    In a well-formed 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 error message to display.
  - yypushback
```
private 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()
```
    Contains user EOF-code, which will be executed exactly once, when the end of file is reached
  - nextChar
```
private int nextChar()
              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.
