| Method Summary | |
| public void | addAuthorization(String authID)
Authorization IDs are not stored by AutoCommit. | | public void | close()
Implements a NOP since AUTO_COMMIT does not maintain State. | | public void | commit()
Implemented as a NOP since this Transaction always commits. | | public Set | getAuthorizations()
Authorization IDs are not stored by AutoCommit. | | public Object | getProperty(Object key)
AutoCommit does not save State. | | public State | getState(Object key)
I am not sure should AutoCommit be able to save sate?
While symetry would be good, state should be commited not stored for
later. | | public void | putProperty(Object key, Object value)
Implementation of addProperty. | | public void | putState(Object key, State state)
AutoCommit does not save State. | | public void | removeState(Object key)
AutoCommit does not save State. | | public void | rollback()
Auto commit mode cannot support the rollback opperation. |
| addAuthorization | | public void addAuthorization(String authID) throws IOException(Code) | | Authorization IDs are not stored by AutoCommit.
Authorization IDs are only stored for the duration of a Transaction.
Parameters:
authID - Authorization ID
throws:
IOException - If set authorization fails |
| close | | public void close()(Code) | | Implements a NOP since AUTO_COMMIT does not maintain State.
|
| commit | | public void commit()(Code) | | Implemented as a NOP since this Transaction always commits.
This allows the following workflow:
Transaction t = roads.getTransaction();
try{
roads.addFeatures( features );
roads.getTransaction().commit();
}
catch( IOException erp ){
//something went wrong;
roads.getTransaction().rollback();
}
