Method Detail

markAsOnePhaseCommit

void markAsOnePhaseCommit()

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.

markSkipWriteSkewCheck

void markSkipWriteSkewCheck()

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.

skipWriteSkewCheck

boolean skipWriteSkewCheck()

Returns:

true when the write skew check is not needed.

getModifications

WriteCommand[] getModifications()

Returns:

the modifications performed by this transaction

getOrCreateState

TotalOrderRemoteTransactionState getOrCreateState()

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

Returns:

returns the TotalOrderRemoteTransactionState associated with this transaction.
