       throws SQLException
        Deprecated.
        Constructor. The raw bytes are computed at this time or a copy of attributes is made. In any event the caller is free to modify the array without affecting the values held in the OPAQUE.
        Parameters:
        type - the SQLStructType used to convert the type to
        attributes - the array specifying the attributes to be converted to raw bytes.
        Throws:
