afterTransaction

public void afterTransaction(TransactionImplementor hibernateTransaction,
                             int status)

Specified by:

afterTransaction in interface TransactionCoordinator

isSynchronizationRegistered

public boolean isSynchronizationRegistered()

Specified by:

isSynchronizationRegistered in interface TransactionCoordinator

isTransactionInProgress

public boolean isTransactionInProgress()

Description copied from interface: TransactionCoordinator

Are we "in" an active and joined transaction

Specified by:

isTransactionInProgress in interface TransactionCoordinator

Returns:

true if there is currently a transaction in progress; false otherwise.

getTransactionContext

public TransactionContext getTransactionContext()

Description copied from interface: TransactionCoordinator

Retrieves the context in which this coordinator operates.

Specified by:

getTransactionContext in interface TransactionCoordinator

Returns:

The context of the coordinator

getJdbcCoordinator

public JdbcCoordinator getJdbcCoordinator()

Description copied from interface: TransactionCoordinator

Retrieves the JDBC coordinator currently operating within this transaction coordinator.

Specified by:

getJdbcCoordinator in interface TransactionCoordinator

Returns:

The JDBC coordinator.

getTransaction

public TransactionImplementor getTransaction()

Description copied from interface: TransactionCoordinator

Get the Hibernate transaction facade object currently associated with this coordinator.

Specified by:

getTransaction in interface TransactionCoordinator

Returns:

The current Hibernate transaction.

afterNonTransactionalQuery

public void afterNonTransactionalQuery(boolean success)

Description copied from interface: TransactionCoordinator

Performs actions needed after execution of a non-transactional query.

Specified by:

afterNonTransactionalQuery in interface TransactionCoordinator

Parameters:

success - Was the query successfully performed

resetJoinStatus

public void resetJoinStatus()

Description copied from interface: TransactionCoordinator

Reset the transaction's join status.

Specified by:

resetJoinStatus in interface TransactionCoordinator

getSynchronizationCallbackCoordinator

public SynchronizationCallbackCoordinator getSynchronizationCallbackCoordinator()

Specified by:

getSynchronizationCallbackCoordinator in interface TransactionCoordinator

pulse

public void pulse()

public Connection close()

Description copied from interface: TransactionCoordinator

Close the transaction context, returning any user supplied connection from the underlying JDBC coordinator.

Specified by:

close in interface TransactionCoordinator

Returns:

The user supplied connection (if one).

getSynchronizationRegistry

public SynchronizationRegistry getSynchronizationRegistry()

Description copied from interface: TransactionCoordinator

Obtain the Synchronization registry associated with this coordinator.

Specified by:

getSynchronizationRegistry in interface TransactionCoordinator

Description copied from interface: TransactionCoordinator

Can we join to the underlying transaction?

Specified by:

isTransactionJoinable in interface TransactionCoordinator

Returns:

true if the underlying transaction can be joined or is already joined; false otherwise.
