Constructor Detail

SubordinateAtomicAction

public SubordinateAtomicAction()

SubordinateAtomicAction

public SubordinateAtomicAction(int timeout)

SubordinateAtomicAction

protected SubordinateAtomicAction(Uid actId)

For crash recovery purposes.

Parameters:

actId - the identifier to recover.

Method Detail

commit

public int commit()

Commit the transaction, and have heuristic reporting. Heuristic reporting via the return code is enabled.

Overrides:

commit in class AtomicAction

Returns:

ActionStatus indicating outcome.

commit

public int commit(boolean report_heuristics)

Commit the transaction. The report_heuristics parameter can be used to determine whether or not heuristic outcomes are reported. If the transaction has already terminated, or has not begun, then an appropriate error code will be returned.

Overrides:

commit in class AtomicAction

Returns:

ActionStatus indicating outcome.

abort

public int abort()

Abort (rollback) the transaction. If the transaction has already terminated, or has not been begun, then an appropriate error code will be returned.

Overrides:

abort in class AtomicAction

Returns:

ActionStatus indicating outcome.

type

public String type()

The type of the class is used to locate the state of the transaction log in the object store. Overloads BasicAction.type()

Overrides:

type in class AtomicAction

Returns:

a string representation of the hierarchy of the class for storing logs in the transaction object store.

doPrepare

public int doPrepare()

doCommit

public int doCommit()

doRollback

public int doRollback()

doOnePhaseCommit

public int doOnePhaseCommit()

doForget

public void doForget()

Deprecated. Only called via tests

doBeforeCompletion

public boolean doBeforeCompletion()

checkForCurrent

protected boolean checkForCurrent()

By default the BasicAction class only allows the termination of a transaction if it's the one currently associated with the thread. We override this here.

Overrides:

checkForCurrent in class AtomicAction

Returns:

false to indicate that this transaction can only be terminated by the right thread.

activated

public boolean activated()
