Class AlphaProgrammaticReferenceTranlocal<E>

java.lang.Object
  org.multiverse.stms.alpha.AlphaTranlocal
      org.multiverse.stms.alpha.programmatic.AlphaProgrammaticReferenceTranlocal<E>

Type Parameters:

E -

All Implemented Interfaces:

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

public final class AlphaProgrammaticReferenceTranlocal<E>
extends AlphaTranlocal
implements org.multiverse.api.Transaction

The AlphaTranlocal for the AlphaProgrammaticReference. It is responsible for storing the state of the AlphaProgrammaticReference.

The AlpaRefTranlocal also implements the Transaction interface because it can be used as a lockOwner. This is done as a performance optimization.

Method Detail

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.

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.

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

public org.multiverse.api.TransactionConfiguration getConfiguration()

Specified by:
