                            throws ConversionException
        Converts the given value to the specified target data type and returns it.
        Conversions between data types.

        Parameters:
        value - the value to be converted; this should typically be a direct equivalent to an ADEPT2 data type. The caller is responsible for closing.
        targetDataType - the target data type to which the value should be converted
        Returns:
        the converted value. The caller is responsible for closing if appropriate.
        Throws:
        ConversionException - if the conversion is not possible
