public final void yypushStream(java.io.Reader reader)
```
    Stores the current input stream on a stack, and reads from a new stream. Lexical state, line, char, and column counting remain untouched. The current input stream can be restored with yypopStream (usually in an <> action).
    
    Parameters:
    
    reader - the new input stream to read from
    
    See Also:
    
    yypopStream()
  - yypopStream
```
public final void yypopStream()
                       throws java.io.IOException
```
    Closes the current input stream and continues to read from the one on top of the stream stack.
    
    Throws:
    
    java.util.EmptyStackException - if there is no further stream to read from.
    
    java.io.IOException - if there was an error in closing the stream.
    
    See Also:
    
    yypushStream(java.io.Reader)
  - yymoreStreams
```
public final boolean yymoreStreams()
```
    Returns true iff there are still streams left to read from on the stream stack.
  - 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
    
    See Also:
    
    yypushStream(java.io.Reader), yypopStream()
  - 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
  - next_token
```
public java_cup.runtime.Symbol next_token()
                                   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.
    
    Specified by:
    
    next_token in interface java_cup.runtime.Scanner
    
    Returns:
    
    the next token
    
    Throws:
    
    java.io.IOException - if any I/O-Error occurs
  - getTokenName
```
private java.lang.String getTokenName(int token)
```
    Converts an int token code into the name of the token by reflection on the cup symbol class/interface sym This code was contributed by Karl Meissner
  - debug_next_token
```
public java_cup.runtime.Symbol debug_next_token()
                                         throws java.io.IOException
```
    Same as next_token but also prints the token to standard out for debugging. This code was contributed by Karl Meissner
    
    Throws:
    
    java.io.IOException
  - main
```
public static void main(java.lang.String[] argv)
```
    Runs the scanner on input files. This main method is the debugging routine for the scanner. It prints debugging information about each returned token to System.out until the end of file is reached, or an error occured.
    
    Parameters:
    
    argv - the command line, contains the filenames to run the scanner on.
