getLockedKeysForRemoteTransaction

public Set<Object> getLockedKeysForRemoteTransaction(GlobalTransaction gtx)

remoteTransactionPrepared

public void remoteTransactionPrepared(GlobalTransaction gtx)

localTransactionPrepared

public void localTransactionPrepared(LocalTransaction localTransaction)

enlist

public void enlist(Transaction transaction,
          LocalTransaction localTransaction)

failureCompletingTransaction

public void failureCompletingTransaction(Transaction tx)

containsLocalTx

public boolean containsLocalTx(Transaction tx)

Returns true if the given transaction is already registered with the transaction table.

Parameters:

tx - if null false is returned

getMinTopologyId

public int getMinTopologyId()

cleanupStaleTransactions

public void cleanupStaleTransactions(CacheTopology cacheTopology)

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,
                                           TxInvocationContext ctx)

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

removeLocalTransaction

public boolean removeLocalTransaction(LocalTransaction localTransaction)

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

removeLocalTransactionInternal

protected final LocalTransaction removeLocalTransactionInternal(Transaction tx)

remoteTransactionCommitted

public void remoteTransactionCommitted(GlobalTransaction gtx,
                              boolean onePc)

Removes the RemoteTransaction corresponding to the given tx.

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 globalTx)

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)

cleanupCompletedTransactions

public void cleanupCompletedTransactions()
