Constructor.
|
Modifier and Type | Method and Description |
---|---|
void |
alter(AbstractRecord a)
Alter the current record with the one presented.
|
static AbstractRecord |
create() |
boolean |
doSave()
Should this record be saved in the intentions list? If the record is
saved, then it may be recovered later in the event of a failure.
|
boolean |
forgetHeuristic()
The record generated a heuristic and can now forget about it.
|
void |
merge(AbstractRecord a)
Merge the current record with the one presented.
|
int |
nestedAbort()
The record is being driven through nested rollback.
|
int |
nestedCommit()
The record is being driven through nested commit.
|
int |
nestedOnePhaseCommit()
The record is being driven through nested commit and is the only
resource.
|
int |
nestedPrepare()
The record is being driven through nested prepare.
|
void |
print(PrintWriter strm)
Write information about this specific instance to the specified stream.
|
boolean |
propagateOnCommit()
Override AbstractRecord.propagateOnCommit
|
void |
readonly() |
boolean |
restore_state(InputObjectState os,
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.
|
void |
rolledback() |
boolean |
save_state(OutputObjectState os,
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)
Set the internal value.
|
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 rec)
Should we replace the record presented with the current record?
|
int |
topLevelAbort()
The record is being driven through top-level rollback.
|
int |
topLevelCommit()
The record is being driven through top-level commit.
|
int |
topLevelOnePhaseCommit()
The record is being driven through top-level commit and is the only
resource.
|
int |
topLevelPrepare()
The record is being driven through top-level prepare.
|
String |
type()
Re-implementation of abstract methods inherited from base class.
|
int |
typeIs()
The type of this abstract record.
|
Object |
value()
The internal value.
