    - #### getParams

          Object[] getParams()
                      throws SQLException

      Retrieves the parameters that have been set for this `RowSet` object's command.
      Returns:
        an array of the current parameter values for this `RowSet` object's command
      Throws:
        `SQLException` - if a database access error occurs

    - #### getConnection

          Connection getConnection()
                            throws SQLException

      Retrieves the `Connection` object that was passed to this `RowSet` object.
      Returns:
        the `Connection` object passed to the rowset or `null` if none was passed
      Throws:
        `SQLException` - if a database access error occurs

    - #### setMetaData

          void setMetaData(RowSetMetaData md)
                    throws SQLException

      Sets the given `RowSetMetaData` object as the `RowSetMetaData` object for this `RowSet` object. The `RowSetReader` object associated with the rowset will use `RowSetMetaData` methods to set the values giving information about the rowset's columns.
      Parameters:
        `md` - the `RowSetMetaData` object that will be set with information about the rowset's columns
      Throws:
        `SQLException` - if a database access error occurs

    - #### getOriginal

          ResultSet getOriginal()
                         throws SQLException

      Retrieves a `ResultSet` object containing the original value of this `RowSet` object.

      The cursor is positioned before the first row in the result set. Only rows contained in the result set returned by the method `getOriginal` are said to have an original value.

      Returns:
        the original value of the rowset
      Throws:
        `SQLException` - if a database access error occurs

    - #### getOriginalRow

          ResultSet getOriginalRow()
                            throws SQLException

      Retrieves a `ResultSet` object containing the original value of the current row only. If the current row has no original value, an empty result set is returned. If there is no current row, an exception is thrown.
      Returns:
        the original value of the current row as a `ResultSet` object
      Throws:
        `SQLException` - if a database access error occurs or this method is called while the cursor is on the insert row, before the first row, or after the last row
