Class AlphaProgrammaticLongTranlocal

java.lang.Object
  org.multiverse.stms.alpha.AlphaTranlocal
      org.multiverse.stms.alpha.programmatic.AlphaProgrammaticLongTranlocal

All Implemented Interfaces:

org.multiverse.api.commitlock.CommitLock, org.multiverse.api.Transaction, org.multiverse.MultiverseConstants

public final class AlphaProgrammaticLongTranlocal
extends AlphaTranlocal
implements org.multiverse.api.Transaction

The AlphaTranlocal for the AlphaProgrammaticLong.

It also implement the transaction interface. This is an optimization needed for the atomic methods, to prevent creating an expensive transaction object.

AlphaProgrammaticLongTranlocal

public AlphaProgrammaticLongTranlocal(AlphaProgrammaticLong transactionalObject,
                                      boolean commuting)

AlphaProgrammaticLongTranlocal

public AlphaProgrammaticLongTranlocal(AlphaProgrammaticLongTranlocal origin)

Method Detail

prematureFixation

public void prematureFixation(AlphaTransaction tx,
                              AlphaTranlocal origin)

Overrides:

prematureFixation in class AlphaTranlocal

lateFixation

public void lateFixation(AlphaTransaction tx)

Overrides:

lateFixation in class AlphaTranlocal

takeSnapshot

public AlphaTranlocalSnapshot takeSnapshot()

Description copied from class: AlphaTranlocal

Creates the TranlocalSnapshot of the Tranlocal. A snapshot should only be made if this Tranlocal is not committed.

Specified by:

takeSnapshot in class AlphaTranlocal

Returns:

the snapshot.

openForWrite

public AlphaTranlocal openForWrite()

Description copied from class: AlphaTranlocal

Returns a clone of this AlphaTranlocal to be used for updates. This method only should be called on tranlocals that have committed (so have a ___writeVersion larger than 0). The implementation is free to check for this violation, but it isn't mandatory.

Specified by:

openForWrite in class AlphaTranlocal

Returns:

the clone of this AlphaTranlocal that can be used for updates.

isDirty

public boolean isDirty()

Description copied from class: AlphaTranlocal

Checks if this Tranlocal should be committed.

Specified by:

isDirty in class AlphaTranlocal

Returns:

true if it should be committed, false otherwise.

abort

public void abort()

Specified by:

abort in interface org.multiverse.api.Transaction

getConfiguration

Specified by:

getStatus in interface org.multiverse.api.Transaction

commit

public void commit()

Specified by:
