/** is used as an output stream for writing the attributes of a user-defined
	type back to the database.  This interface, used only for custom mapping,
	is used by the driver, and its methods are never directly invoked
	by a programmer.


	<p>
	When an object of a class implementing interface
	<type scope="com::sun::star::sdbc">XSQLData</type>
	is passed as an argument to a SQL statement, the JDBC driver calls
	<method scope="com::sun::star::sdbc">SQLData::getSQLType</method>
	to determine the kind of SQL datum being passed to the database.
	<br/>
	The driver then creates an instance of
	<code>XSQLOutput</code>
	and passes it to the method
	<method scope="com::sun::star::sdbc">XSQLData::writeSQL</method>
	. The method
	<code>writeSQL</code>
	in turn calls the appropriate
	<code>XSQLOutput.writeXXX</code>
	methods to write data from the
	<type scope="com::sun::star::sdbc">XSQLData</type>
	object to the
	<code>XSQLOutput</code>
	output stream as the representation of a SQL user-defined type.</p>
