 * However, applications will have the means to specify at runtime the
 * desired <code>SyncProvider</code> object.
 * <p>
 * For example, creating a <code>CachedRowSetImpl</code> object as follows ensures
 * that a it is established with the <code>com.foo.provider.Impl</code> synchronization
 * implementation providing the synchronization mechanism for this disconnected
 * <code>RowSet</code> object.
 * <pre>
 *     Hashtable env = new Hashtable();
 *     env.put(javax.sql.rowset.spi.SyncFactory.ROWSET_PROVIDER_NAME,
 *         "com.foo.provider.Impl");
 *     CachedRowSetImpl crs = new CachedRowSet(env);
 * </pre>
 * <p>
 * Calling this constructor with a <code>null</code> parameter will
 * cause the <code>SyncFactory</code> to provide the reference
 * optimistic provider <code>com.sun.rowset.providers.RIOptimisticProvider</code>.
 * <p>
 * In addition, the following properties can be associated with the
 * provider to assist in determining the choice of the synchronizaton
 * provider such as:
 * <ul>
 * <li><code>ROWSET_SYNC_PROVIDER</code> - the property specifying the the
 * <code>SyncProvider</code> class name to be instantiated by the
 * <code>SyncFacttory</code>
 * <li><code>ROWSET_SYNC_VENDOR</code> - the property specifying the software
 * vendor associated with a <code>SyncProvider</code> implementation.
 * <li><code>ROWSET_SYNC_PROVIDER_VER</code> - the property specifying the
 * version of the <code>SyncProvider</code> implementation provided by the
 * software vendor.
 * </ul>
 * More specific detailes are available in the <code>SyncFactory</code>
 * and <code>SyncProvider</code> specificiations later in this document.
 * <p>
 * @param env a <code>Hashtable</code> object with a list of desired
 *        synchronization providers
 * @throws SQLException if the requested provider cannot be found by the
 * synchonization factory
 * @see SyncProvider
