 * transaction control.
 * <p>
 * If one or more disconnected <code>RowSet</code> objects are participating
 * in a global transaction, they may wish to coordinate their synchronization
 * commits to preserve data integrity and reduce the number of
 * synchronization exceptions. If this is the case, an application should set
 * the <code>CachedRowSet</code> constant <code>COMMIT_ON_ACCEPT_CHANGES</code>
 * to <code>false</code> and use the <code>commit</code> and <code>rollback</code>
 * methods defined in this interface to manage transaction boundaries.
