Method Detail

getCommandId

public byte getCommandId()

Description copied from interface: ReplicableCommand

Used by marshallers to convert this command into an id for streaming.

Specified by:

getCommandId in interface ReplicableCommand

Overrides:

getCommandId in class PrepareCommand

Returns:

the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

markAsOnePhaseCommit

public void markAsOnePhaseCommit()

Description copied from interface: TotalOrderPrepareCommand

marks the prepare phase as 1PC to apply immediately the modifications. It is used when the org.infinispan.commands.tx.CommitCommand is received before the org.infinispan.commands.tx.PrepareCommand.

Specified by:

markAsOnePhaseCommit in interface TotalOrderPrepareCommand

markSkipWriteSkewCheck

public void markSkipWriteSkewCheck()

Description copied from interface: TotalOrderPrepareCommand

it signals that the write skew check is not needed (for versioned entries). It is used when the org.infinispan.commands.tx.CommitCommand is received before the org.infinispan.commands.tx.PrepareCommand.

Specified by:

markSkipWriteSkewCheck in interface TotalOrderPrepareCommand

skipWriteSkewCheck

public boolean skipWriteSkewCheck()

Specified by:

skipWriteSkewCheck in interface TotalOrderPrepareCommand

Returns:

true when the write skew check is not needed.

getOrCreateState

public TotalOrderRemoteTransactionState getOrCreateState()

Description copied from interface: TotalOrderPrepareCommand

returns the TotalOrderRemoteTransactionState associated with this transaction, creating one if no one was associated to this transaction.

Specified by:

getOrCreateState in interface TotalOrderPrepareCommand

Returns:

returns the TotalOrderRemoteTransactionState associated with this transaction.
