/**
 * The reference implementation of a JDBC Rowset synchronization provider
 * providing optimistic synchronization with a relational datastore
 * using any JDBC technology-enabled driver.
 *
 * <h3>1.0 Backgroud</h3>
 * This synchronization provider is registered with the
 * <code>SyncFactory</code> by default as the
 * <code>com.sun.rowset.providers.RIOptimisticProvider</code>.
 * As an extension of the <code>SyncProvider</code> abstract
 * class, it provides the reader and writer classes required by disconnected
 * rowsets as <code>javax.sql.RowSetReader</code> and <code>javax.sql.RowSetWriter</code>
 * interface implementations. As a reference implementation,
 * <code>RIOptimisticProvider</code> provides a
 * fully functional implementation offering a medium grade classification of
 * syncrhonization, namely GRADE_CHECK_MODIFIED_AT_COMMIT. A
 * disconnected <code>RowSet</code> implementation using the
 * <code>RIOptimisticProvider</code> can expect the writer to
 * check only rows that have been modified in the <code>RowSet</code> against
 * the values in the data source.  If there is a conflict, that is, if a value
 * in the data source has been changed by another party, the
 * <code>RIOptimisticProvider</code> will not write any of the changes to the data
 * source and  will throw a <code>SyncProviderException</code> object.
 *
 * <h3>2.0 Usage</h3>
 * Standard disconnected <code>RowSet</code> implementations may opt to use this
 * <code>SyncProvider</code> implementation in one of two ways:
 * <OL>
 *  <LI>By specifically calling the <code>setSyncProvider</code> method
    defined in the <code>CachedRowSet</code> interface
 * <pre>
 *     CachedRowset crs = new FooCachedRowSetImpl();
 *     crs.setSyncProvider("com.sun.rowset.providers.RIOptimisticProvider");
 * </pre>
 *  <LI>By specifying it in the constructor of the <code>RowSet</code>
 *      implementation
 * <pre>
 *     CachedRowset crs = new FooCachedRowSetImpl(
 *                         "com.sun.rowset.providers.RIOptimisticProvider");
 * </pre>
 * </OL>
 * Note that because the <code>RIOptimisticProvider</code> implementation is
 * the default provider, it will always be the provider when no provider ID is
 * specified to the constructor.
 * <P>
 * See the standard <code>RowSet</code> reference implementations in the
 * <code>com.sun.rowset</code> package for more details.
