+/**
+ * The mapping in the Java™ programming language
+ * for the SQL <code>NCLOB</code> type.
+ * An SQL <code>NCLOB</code> is a built-in type
+ * that stores a Character Large Object using the National Character Set
+ *  as a column value in a row of  a database table.
+ * <P>The <code>NClob</code> interface extends the <code>Clob</code> interface
+ * which provides methods for getting the
+ * length of an SQL <code>NCLOB</code> value,
+ * for materializing a <code>NCLOB</code> value on the client, and for
+ * searching for a substring or <code>NCLOB</code> object within a
+ * <code>NCLOB</code> value. A <code>NClob</code> object, just like a <code>Clob</code> object, is valid for the duration
+ * of the transaction in which it was created.
+ * Methods in the interfaces {@link ResultSet},
+ * {@link CallableStatement}, and {@link PreparedStatement}, such as
+ * <code>getNClob</code> and <code>setNClob</code> allow a programmer to
+ * access an SQL <code>NCLOB</code> value.  In addition, this interface
+ * has methods for updating a <code>NCLOB</code> value.
+ * <p>
+ * All methods on the <code>NClob</code> interface must be fully implemented if the
+ * JDBC driver supports the data type.
+ *
+ * @since 1.6
