      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

      public final int yystate()
      Returns the current lexical state.

      Returns the text matched by the current regular expression.

      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 IOException
      Contains user EOF-code, which will be executed exactly once, when the end of file is reached
      Throws:
      IOException
    • 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
