         * An input stream that contains a stream of values representing an
         * instance of an SQL structured type or an SQL distinct type.
         * This interface, used only for custom mapping, is used by the driver
         * behind the scenes, and a programmer never directly invokes
         * <code>SQLInput</code> methods. The <i>reader</i> methods
         * (<code>readLong</code>, <code>readBytes</code>, and so on)
         * provide a way  for an implementation of the <code>SQLData</code>
         * interface to read the values in an <code>SQLInput</code> object.
         * And as described in <code>SQLData</code>, calls to reader methods must
         * be made in the order that their corresponding attributes appear in the
         * SQL definition of the type.
         * The method <code>wasNull</code> is used to determine whether
         * the last value read was SQL <code>NULL</code>.
         * <P>When the method <code>getObject</code> is called with an
         * object of a class implementing the interface <code>SQLData</code>,
         * the JDBC driver calls the method <code>SQLData.getSQLType</code>
         * to determine the SQL type of the user-defined type (UDT)
         * being custom mapped. The driver
         * creates an instance of <code>SQLInput</code>, populating it with the
         * attributes of the UDT.  The driver then passes the input
         * stream to the method <code>SQLData.readSQL</code>, which in turn
         * calls the <code>SQLInput</code> reader methods
         * in its implementation for reading the
