/** 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
    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>.
