      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()!
    • yylex

      public int yylex() throws 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:
      IOException - if any I/O-Error occurs
