/** is the mapping for the SQL
	<code>CLOB</code>
	type.


	<p>
	A SQL
	<code>CLOB</code>
	is a built-in type
	that stores a Character Large Object as a column value in a row of
	a database table.
	The driver implements a
	<code>Clob</code>
	object using a SQL
	<code>locator(CLOB)</code>
	, which means that a
	<code>Clob</code>
	object
	contains a logical pointer to the SQL
	<code>CLOB</code>
	data rather than
	the data itself. A
	<code>Clob</code>
	object is valid for the duration
	of the transaction in which it was created.
	</p>
	<p>
	The
	<code>Clob</code>
	interface provides methods for getting the
	length of a SQL
	<code>CLOB</code>
	(Character Large Object) value,
	for materializing a
	<code>CLOB</code>
	value on the client, and for
	searching for a substring or
	<code>CLOB</code>
	object within a
	<code>CLOB</code>
	value.
	</p>
	<p>
	Methods in the interfaces
	<type scope="com::sun::star::sdbc">XResultSet</type>
	,
	and
	<type scope="com::sun::star::sdbc">XPreparedStatement</type>
	, such as
	<code>getClob</code>
	and
	<code>setClob</code>
	allow a programmer to
	access the SQL
	<code>CLOB</code>
	.
