    /**
     * Returns a SyncProvider instance. Once invoked a RowSet implementation
     * should then be able to call the Reader and Writer methods of this
     * instance to obtain handles back to the datasource.
     *
     * @param providerID the unique identifier of the provider
     * @throws SyncFactoryException If the SyncProvider cannot be found or
     * some error was encountered when trying to invoke this provider.
     * @return SyncProvider A <code>SyncProvider</code> implementation.
