void |
alter(AbstractRecord a)
Alter the current record with the one presented.
|
boolean |
isReadOnly() |
String |
lockType() |
void |
merge(AbstractRecord a)
Merge the current record with the one presented.
|
int |
nestedAbort()
A rollback of a nested transaction has occurred.
|
int |
nestedCommit()
A commit of a nested transaction has occurred.
|
int |
nestedPrepare()
A prepare for a nested transaction has occurred.
|
void |
print(PrintWriter strm)
Write information about this specific instance to the specified stream.
|
boolean |
restore_state(InputObjectState o,
int t)
During recovery, the transaction log is given to the recovery system and
it will recreate a transaction instance to perform necessary recovery
actions.
|
boolean |
save_state(OutputObjectState o,
int t)
When the transaction is required to make the intentions list persistent,
it scans the list and asks each record whether or not it requires state
to be saved (by calling doSave).
|
void |
setValue(Object o) |
boolean |
shouldAdd(AbstractRecord a)
Should we add the record presented to the intentions list?
|
boolean |
shouldAlter(AbstractRecord a)
Should we alter the current record with the one presented?
|
boolean |
shouldMerge(AbstractRecord a)
Should we merge the current record with the one presented?
|
boolean |
shouldReplace(AbstractRecord ar)
Should we replace the record presented with the current record?
|
int |
topLevelAbort()
A rollback of a top-level transaction has occurred.
|
int |
topLevelCommit()
A commit of a top-level transaction has occurred.
|
int |
topLevelPrepare()
A prepare for a top-level transaction has occurred.
