/** is the mapping for the SQL

<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
com::sun::star::sdbc::XResultSet
,
and
com::sun::star::sdbc::XPreparedStatement
, such as
<code>getClob</code>
and
<code>setClob</code>
allow a programmer to access the SQL <code>CLOB</code>.
