    • report_error

      public void report_error(String message, Object info)
      Description copied from class: lr_parser
      Report a non fatal error (or warning). This method takes a message string and an additional object (to be used by specializations implemented in subclasses). Here in the base class a very simple implementation is provided which simply prints the message to System.err.
      Overrides:
      report_error in class lr_parser
      Parameters:
      message - an error message.
      info - an extra object reserved for use by specialized subclasses.

    • report_error

      public void report_error(String message, int line)

    • syntax_error

      public void syntax_error(Symbol cur_token)
      Description copied from class: lr_parser
      This method is called when a syntax error has been detected and recovery is about to be invoked. Here in the base class we just emit a "Syntax error" error message.
      Overrides:
      syntax_error in class lr_parser
      Parameters:
      cur_token - the current lookahead Symbol.

    • report_fatal_error

      public void report_fatal_error(String message, Object info)
      Description copied from class: lr_parser
      Report a fatal error. This method takes a message string and an additional object (to be used by specializations implemented in subclasses). Here in the base class a very simple implementation is provided which reports the error then throws an exception.
      Overrides:
      report_fatal_error in class lr_parser
      Parameters:
      message - an error message.
      info - an extra object reserved for use by specialized subclasses.
