/**
 * 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
 * attributes from the input stream.
