Parameters:

transaction - the transaction

Returns:

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

Throws:

jakarta.transaction.SystemException

isImported

public boolean isImported(@NotNull
                          jakarta.transaction.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
                                                       jakarta.transaction.Transaction transaction,

getKey

@NotNull
public abstract Object getKey(@NotNull

dropLocal

public void dropLocal(@NotNull
                      jakarta.transaction.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
                       jakarta.transaction.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)

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
                           jakarta.transaction.Transaction transaction)

Description copied from interface: LocalTransactionProvider

Get the transaction ID of the given transaction.

Specified by:

                             Xid xid)

Specified by:

getNameFromXid in interface LocalTransactionProvider

Parameters:

xid - the XID (not null)

Returns:

the originating node name

getProviderInterface

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