35Provides five standard implementations of the standard JDBC <code>RowSet</code> implementation
36interface definitions. These reference implementations are included with the J2SE version
371.5 platform and represent the benchmark standard <code>RowSet</code> implementations as verified
38by the Test Compatibility Kit (TCK) as mandated by the Java Community Process.
39<br>

41<h3>1.0 Available JDBC RowSet Reference Implementations </h3>
42The following implementations are provided:<br>
43
44<blockquote><code><b>JdbcRowSetImpl</b></code> - The <code>javax.sql.rowset.JdbcRowSet</code>
45interface reference implementation. <br>
46<br>
47<code><b>CachedRowSetImpl</b></code> - The <code>javax.sql.rowset.CachedRowSet</code> interface
48reference implementation.<br>
49<br>
50<code><b>WebRowSetImpl</b></code> - The <code>javax.sql.rowset.WebRowSet</code> interface
51reference implementation.<br>
52<br>
53<code><b>FilteredRowSetImpl</b></code> - The <code>javax.sql.rowset.FilteredRowSet</code>
54interface reference implementation.<br>
55<br>
56<code><b>JoinRowSetImpl</b></code> - The <code>javax.sql.rowset.JoinRowSet</code> interface
57reference implementation.<br>
58</blockquote>
59
60All details on their expected behavior, including their interactions with the <code>SyncProvider</code>
61SPI and helper classes are provided in the interface definitions in the <code>javax.sql.rowset</code>
62package specification.<br>
63
64<h3>2.0 Usage</h3>
65The reference implementations represent robust implementations of the standard
66<code>RowSet</code> interfaces defined in the <code>javax.sql.rowset</code> package.
67All disconnected <code>RowSet</code> implementations, such as the <code>CachedRowSetImpl</code>
68and <code>WebRowSetImpl</code>, are flexible enough to use the <code>SyncFactory</code> SPIs to
69leverage non-reference implementation <code>SyncProvider</code> implementations to obtain
70differing synchronization semantics. Furthermore, developers and vendors alike are free
71to use these implementations and integrate them into their products just as they
72can with to other components of the Java platform.<br>
73
74<h3>3.0 Extending the JDBC RowSet Implementations</h3>
75
76The JDBC <code>RowSet</code> reference implementations are provided as non-final
77classes so that any developer can extend them to provide additional features
78while maintaining the core required standard functionality and compatibility. It
79is anticipated that many vendors and developers will extend the standard feature
80set to their their particular needs. The website for JDBC Technology will
81provider a portal where implementations can be listed, similar to the way it
82provides a site for JDBC drivers.
