@NotNull
public Transaction createNewTransaction(int timeout)
                                 throws SystemException,
                                        SecurityException

Description copied from interface: LocalTransactionProvider

Create and start a new local transaction, which is not associated with any particular thread.

Specified by:

createNewTransaction in interface LocalTransactionProvider

Parameters:

timeout - the timeout to use for the new transaction

Returns:

the new transaction (must not be null)

Throws:

SystemException - if the creation of the transaction failed for some reason

SecurityException - if the caller is not authorized to create a transaction

getXAResourceRegistry

public XAResourceRegistry getXAResourceRegistry(LocalTransaction transaction)
                                         throws SystemException

Description copied from interface: LocalTransactionProvider

Return the XAResource registry associated with transaction. If there is no such registry yet, one is created.

Specified by:

getXAResourceRegistry in interface LocalTransactionProvider

Parameters:

transaction - the transaction

Returns:

the registry associated with transaction. Can return null if this provider requires no XAResource registry

Throws:

SystemException

isImported

public boolean isImported(@NotNull
                          Transaction transaction)
                   throws IllegalArgumentException

Description copied from interface: LocalTransactionProvider

Determine whether the given transaction was imported or originated locally.

Specified by:

isImported in interface LocalTransactionProvider

Parameters:

transaction - the transaction to test (not null)

Returns:

true if the transaction was imported, or false if it was created locally

Throws:

IllegalArgumentException - if the transaction does not belong to this provider

registerInterposedSynchronization

public abstract void registerInterposedSynchronization(@NotNull
                                                       Transaction transaction,
                                                       @NotNull
                                                       Synchronization sync)
                                                throws IllegalArgumentException

Specified by:

registerInterposedSynchronization in interface LocalTransactionProvider

Parameters:

transaction - the transaction (not null)

sync - the synchronization (not null)

Throws:

IllegalArgumentException - if the transaction does not belong to this provider

getKey

@NotNull
public abstract Object getKey(@NotNull
                              Transaction transaction)
                       throws IllegalArgumentException

Description copied from interface: LocalTransactionProvider

Get a key which has the same equals and hashCode behavior as the given transaction.

Specified by:

getKey in interface LocalTransactionProvider

Parameters:

transaction - the transaction (not null)

Returns:

the key object (must not be null)

Throws:

dropLocal

public void dropLocal(@NotNull
                      Transaction transaction)

Description copied from interface: LocalTransactionProvider

Drop a local transaction from memory. The transaction is locally-initiated and contains no remote subordinate enlistments, guaranteeing that the transaction can never reappear on this node.

Specified by:

dropLocal in interface LocalTransactionProvider

Parameters:

transaction - the transaction to drop (not null)

dropRemote

public void dropRemote(@NotNull
                       Transaction transaction)

Description copied from interface: LocalTransactionProvider

The transaction is expected to work with outflowed resources - it contains a remote subordinate enlistment. We can't use the LocalTransactionProvider.dropLocal(Transaction) directly as the the transaction may reapear on this node during recovery. But this method gives a chance to the provider to reassign the removal timeout or some other work that needs to be done in case the in-flight transaction finished.

Specified by:

dropRemote in interface LocalTransactionProvider

Parameters:

transaction - the transaction with ouflowed resources to announce of being finished (not null)

getTimeout

public abstract int getTimeout(@NotNull
                               Transaction transaction)

Description copied from interface: LocalTransactionProvider

Get the configured timeout of the given transaction (not the remaining time).

Specified by:

getTimeout in interface LocalTransactionProvider

Parameters:

transaction - the transaction (not null)

Returns:

the number of seconds remaining

getXid

@NotNull
public abstract Xid getXid(@NotNull
                           Transaction transaction)

Description copied from interface: LocalTransactionProvider

Get the transaction ID of the given transaction.

Specified by:

getXid in interface LocalTransactionProvider

Parameters:

transaction - the transaction (not null)

Returns:

the transaction ID (must not be null)

getNodeName

@NotNull
public String getNodeName()

Description copied from interface: LocalTransactionProvider

Get the unique node name of this provider.

Specified by:

getNodeName in interface LocalTransactionProvider

Returns:

the node name (must not be null)

public String getNameFromXid(@NotNull
                             Xid xid)

Specified by:

getNameFromXid in interface LocalTransactionProvider

Parameters:

xid - the XID (not null)

Returns:

the originating node name

getProviderInterface

public <T> T getProviderInterface(Transaction transaction,
                                  Class<T> providerInterfaceType)
