Method Detail

start

public void start()

getGlobalTransaction

public GlobalTransaction getGlobalTransaction(Transaction transaction)

Specified by:

getGlobalTransaction in interface TransactionTable

Parameters:

transaction - the local transaction. Must be non-null.

Returns:

the GlobalTransaction associated with the transaction or null if doesn't exists.

getLocalGlobalTransaction

public Collection<GlobalTransaction> getLocalGlobalTransaction()

Specified by:

getLocalGlobalTransaction in interface TransactionTable

Returns:

an unmodified collection of GlobalTransaction associated with local running transactions.

getRemoteGlobalTransaction

public Collection<GlobalTransaction> getRemoteGlobalTransaction()

Specified by:

getRemoteGlobalTransaction in interface TransactionTable

Returns:

an unmodified collection of GlobalTransaction associated with remote transactions.

remoteTransactionPrepared

public void remoteTransactionPrepared(GlobalTransaction gtx)

localTransactionPrepared

public void localTransactionPrepared(LocalTransaction localTransaction)

enlist

public void enlist(Transaction transaction,
                   LocalTransaction localTransaction)

enlistClientTransaction

public void enlistClientTransaction(Transaction transaction,
                                    LocalTransaction localTransaction)

failureCompletingTransaction

public void failureCompletingTransaction(Transaction tx)

getMinTopologyId

public int getMinTopologyId()

cleanupLeaverTransactions

public void cleanupLeaverTransactions(List<Address> members)

remoteTransactionCommitted

public void remoteTransactionCommitted(GlobalTransaction gtx,
                                       boolean onePc)

Removes the RemoteTransaction corresponding to the given tx.

onViewChange

public void onViewChange(ViewChangedEvent e)

getRemoteTransaction

public RemoteTransaction getRemoteTransaction(GlobalTransaction txId)

Returns the RemoteTransaction associated with the supplied transaction id. Returns null if no such association exists.

remoteTransactionRollback

public void remoteTransactionRollback(GlobalTransaction gtx)

getOrCreateRemoteTransaction

public RemoteTransaction getOrCreateRemoteTransaction(GlobalTransaction globalTx,
                                                      WriteCommand[] modifications)

Returns an existing remote transaction or creates one if none exists. Atomicity: this method supports concurrent invocations, guaranteeing that all threads will see the same transaction object.

getOrCreateLocalTransaction

public LocalTransaction getOrCreateLocalTransaction(Transaction transaction,
                                                    boolean implicitTransaction)

Returns the TransactionXaAdapter corresponding to the supplied transaction. If none exists, will be created first.

getOrCreateLocalTransaction

public LocalTransaction getOrCreateLocalTransaction(Transaction transaction,
                                                    boolean implicitTransaction,
                                                    Supplier<GlobalTransaction> gtxFactory)

Similar to getOrCreateLocalTransaction(Transaction, boolean) but with a custom global transaction factory.

removeLocalTransaction

public boolean removeLocalTransaction(LocalTransaction localTransaction)

Removes the TransactionXaAdapter corresponding to the given tx. Returns true if such an tx exists.

removeRemoteTransaction

public final RemoteTransaction removeRemoteTransaction(GlobalTransaction txId)

getRemoteTxCount

public int getRemoteTxCount()

getLocalTxCount

public int getLocalTxCount()

getLocalTransaction

public LocalTransaction getLocalTransaction(GlobalTransaction txId)

Looks up a LocalTransaction given a GlobalTransaction.

Parameters:

txId - the global transaction identifier

Returns:

the LocalTransaction or null if not found

containsLocalTx

public boolean containsLocalTx(GlobalTransaction globalTransaction)

getLocalTransaction

public LocalTransaction getLocalTransaction(Transaction tx)

containRemoteTx

public boolean containRemoteTx(GlobalTransaction globalTransaction)

getRemoteTransactions

public Collection<RemoteTransaction> getRemoteTransactions()

getLocalTransactions

public Collection<LocalTransaction> getLocalTransactions()

recalculateMinTopologyIdIfNeeded

protected final void recalculateMinTopologyIdIfNeeded(CacheTransaction removedTransaction)

onTopologyChange

public void onTopologyChange(TopologyChangedEvent<?,?> tce)

markTransactionCompleted

public void markTransactionCompleted(GlobalTransaction gtx,
                                     boolean successful)

With the current state transfer implementation it is possible for a transaction to be prepared several times on a remote node. This might cause leaks, e.g. if the transaction is prepared, committed and prepared again. Once marked as completed (because of commit or rollback) any further prepare received on that transaction are discarded.

isTransactionCompleted

public boolean isTransactionCompleted(GlobalTransaction gtx)

markTransactionCompleted(org.infinispan.transaction.xa.GlobalTransaction, boolean)

getCompletedTransactionStatus

public TransactionTable.CompletedTransactionStatus getCompletedTransactionStatus(GlobalTransaction gtx)

See Also:

markTransactionCompleted(org.infinispan.transaction.xa.GlobalTransaction, boolean)

beforeCompletion

public CompletionStage<Integer> beforeCompletion(LocalTransaction localTransaction)

afterCompletion

public CompletionStage<Void> afterCompletion(LocalTransaction localTransaction,
                                             int status)

releaseLocksForCompletedTransaction

protected final void releaseLocksForCompletedTransaction(LocalTransaction localTransaction,
                                                         boolean committedInOnePhase)
