/** |
|
36 |
* A specialized interface that facilitates an extension of the standard |
|
37 |
* <code>SyncProvider</code> abstract class so that it has finer grained |
|
38 |
* transaction control. |
|
39 |
* <p> |
|
21278 | 40 |
* If one or more disconnected <code>RowSet</code> objects are participating |
2 | 41 |
* in a global transaction, they may wish to coordinate their synchronization |
42 |
* commits to preserve data integrity and reduce the number of |
|
21278 | 43 |
* synchronization exceptions. If this is the case, an application should set |
2 | 44 |
* the <code>CachedRowSet</code> constant <code>COMMIT_ON_ACCEPT_CHANGES</code> |
45 |
* to <code>false</code> and use the <code>commit</code> and <code>rollback</code> |
|
46 |
* methods defined in this interface to manage transaction boundaries. |
