nestedAbort
public int nestedAbort()nestedAbort causes the reset_state function of the object to be invoked passing it the saved ObjectStatus.- Specified by:
nestedAbort
in classAbstractRecord
- Returns:
TwoPhaseOutcome

nestedCommit
in classAbstractRecord
- Returns:
TwoPhaseOutcome
to indicate success/failure.- See Also:
-
nestedPrepare
public int nestedPrepare()Description copied from class:AbstractRecord
A prepare for a nested transaction has occurred.- Specified by:
nestedPrepare
in classAbstractRecord
- Returns:
TwoPhaseOutcome
to indicate success/failure.- See Also:
-
topLevelAbort
public int topLevelAbort()topLevelAbort for Activation records is exactly like a nested abort.- Specified by:
topLevelAbort
in classAbstractRecord
- Returns:
TwoPhaseOutcome
to indicate success/failure.- See Also:

topLevelCommit
public int topLevelCommit()Description copied from class:AbstractRecord
A commit of a top-level transaction has occurred.- Specified by:
topLevelCommit
in classAbstractRecord
- Returns:
TwoPhaseOutcome
to indicate success/failure.- See Also:
-
topLevelPrepare
public int topLevelPrepare()Description copied from class:AbstractRecord
A prepare for a top-level transaction has occurred.- Specified by:
topLevelPrepare
