58/** represents an input stream that contains a stream of values representing an
59    instance of a SQL structured or distinct type.
60
61
62    <p>
63    This interface, used only for custom mapping, is used by the driver
64    behind the scenes, and a programmer never directly invokes
65    <code>SQLInput</code>
66    methods.
67    </p>
68    <p>
69    When the method
70    <code>getObject</code>
71    is called with an object of a service implementing the interface
72    <code>SQLData</code>
73    , the SDBC driver calls the method
74    <member scope="com::sun::star::sdbc">XSQLData::getSQLType()</member>
75    to determine the SQL type of the user-defined type (UDT) being custom mapped.
76    The driver creates an instance of
77    <type scope="com::sun::star::sdbc">XSQLInput</type>
78    ,
79    populating it with the attributes of the UDT. The driver then passes the input
80    stream to the method
81    <member scope="com::sun::star::sdbc">XSQLData::readSQL()</member>
82    , which in turn calls the
83    <code>XSQLInput.readXXX</code>
84    methods in its implementation for reading the attributes from the input stream.
85    </p>
