Method Details

getTransactionDriverControl

public TransactionCoordinator.TransactionDriver getTransactionDriverControl()

Description copied from interface: TransactionCoordinator

Get the delegate used by the local transaction driver to control the underlying transaction

Specified by:

getTransactionDriverControl in interface TransactionCoordinator

Returns:

The control delegate.

explicitJoin

public void explicitJoin()

Description copied from interface: TransactionCoordinator

Indicates an explicit request to join a transaction. This is mainly intended to handle the JPA requirement around EntityManager.joinTransaction(), and generally speaking only has an impact in JTA environments

Specified by:

explicitJoin in interface TransactionCoordinator

isJoined

public boolean isJoined()

Description copied from interface: TransactionCoordinator

Determine if there is an active transaction that this coordinator is already joined to.

Specified by:

isJoined in interface TransactionCoordinator

Returns:

true if there is an active transaction this coordinator is already joined to; false otherwise.

pulse

public void pulse()

Description copied from interface: TransactionCoordinator

Used by owner of the "JDBC session" as a means to indicate that implicit joining should be done if needed.

Specified by:

pulse in interface TransactionCoordinator

getLocalSynchronizations

public SynchronizationRegistry getLocalSynchronizations()

Description copied from interface: TransactionCoordinator

Get access to the local registry of Synchronization instances

Specified by:

getLocalSynchronizations in interface TransactionCoordinator

Returns:

The local Synchronization registry

getJpaCompliance

public JpaCompliance getJpaCompliance()

Specified by:

getJpaCompliance in interface TransactionCoordinator

isActive

public boolean isActive()

Description copied from interface: TransactionCoordinator

Is this transaction still active?

Answers on a best-effort basis. For example, in the case of JDBC based transactions we cannot know that a transaction is active when it is initiated directly through the JDBC Connection, only when it is initiated from here.

Specified by:

isActive in interface TransactionCoordinator

Returns:

true if the transaction is still active; false otherwise.

createIsolationDelegate

public IsolationDelegate createIsolationDelegate()

Description copied from interface: TransactionCoordinator

Retrieve an isolation delegate appropriate for this transaction strategy.

Specified by:

createIsolationDelegate in interface TransactionCoordinator

Returns:

An isolation delegate.

getTransactionCoordinatorBuilder

public TransactionCoordinatorBuilder getTransactionCoordinatorBuilder()

Description copied from interface: TransactionCoordinator

Access to the builder that generated this coordinator

Specified by:

getTransactionCoordinatorBuilder in interface TransactionCoordinator

setTimeOut

public void setTimeOut(int seconds)

Specified by:

setTimeOut in interface TransactionCoordinator

getTimeOut

public int getTimeOut()

Specified by:

getTimeOut in interface TransactionCoordinator

addObserver

public void addObserver(TransactionObserver observer)

Description copied from interface: TransactionCoordinator

Adds an observer to the coordinator.

Observers are not to be cleared on transaction completion.

Specified by:

addObserver in interface TransactionCoordinator

Parameters:

observer - The observer to add.

removeObserver

public void removeObserver(TransactionObserver observer)

Description copied from interface: TransactionCoordinator

Remove an observer from the coordinator.

Specified by:

removeObserver in interface TransactionCoordinator

Parameters:

observer - The observer to remove.
