Method Details

propagateOnAbort

public boolean propagateOnAbort()

Description copied from class: AbstractRecord

Determine if records are discarded on action abort or must be propagated to parents.

Overrides:

propagateOnAbort in class AbstractRecord

Returns:

true if the record should be propagated to the parent transaction if the current transaction rolls back, false otherwise. The default is false.

nestedAbort

public int nestedAbort()

Description copied from class: ActivationRecord

nestedAbort causes the reset_state function of the object to be invoked passing it the saved ObjectStatus.

Overrides:

nestedAbort in class ActivationRecord

Returns:

TwoPhaseOutcome to indicate success/failure.

See Also:

• TwoPhaseOutcome

nestedCommit

public int nestedCommit()

Description copied from class: ActivationRecord

nestedCommit does nothing since the passing of the state up to the parent action is handled by the record list merging system. In fact since nested_prepare returns PREPARE_READONLY this function should never actually be called.

Overrides:

nestedCommit in class ActivationRecord

Returns:

TwoPhaseOutcome to indicate success/failure.

See Also:

• TwoPhaseOutcome

nestedPrepare

public int nestedPrepare()

Description copied from class: AbstractRecord

A prepare for a nested transaction has occurred.

Overrides:

nestedPrepare in class ActivationRecord

Returns:

TwoPhaseOutcome to indicate success/failure.

See Also:

• TwoPhaseOutcome

topLevelAbort

public int topLevelAbort()

Description copied from class: ActivationRecord

topLevelAbort for Activation records is exactly like a nested abort.

Overrides:

topLevelAbort in class ActivationRecord

Returns:

TwoPhaseOutcome to indicate success/failure.

See Also:

• TwoPhaseOutcome

topLevelCommit

public int topLevelCommit()

Description copied from class: AbstractRecord

A commit of a top-level transaction has occurred.

Overrides:

topLevelCommit in class ActivationRecord

Returns:

TwoPhaseOutcome to indicate success/failure.

See Also:

• TwoPhaseOutcome

topLevelPrepare

public int topLevelPrepare()

Description copied from class: AbstractRecord

A prepare for a top-level transaction has occurred.

Overrides:

topLevelPrepare in class ActivationRecord

Returns:

TwoPhaseOutcome to indicate success/failure.

See Also:

• TwoPhaseOutcome

type

public String type()

Description copied from class: AbstractRecord

Re-implementation of abstract methods inherited from base class.

Overrides:

type in class ActivationRecord

shouldReplace

public boolean shouldReplace(AbstractRecord ar)

Description copied from class: AbstractRecord

Should we replace the record presented with the current record?

Overrides:

shouldReplace in class ActivationRecord

Parameters:

ar - The record to try to replace.

Returns:

true if the record should be replaced, false otherwise.
