Method Detail

doBegin

protected void doBegin()

Description copied from class: AbstractTransactionImpl

Perform the actual steps of beginning a transaction according to the strategy.

Specified by:

doBegin in class AbstractTransactionImpl

afterTransactionBegin

protected void afterTransactionBegin()

Specified by:

afterTransactionBegin in class AbstractTransactionImpl

beforeTransactionCommit

protected void beforeTransactionCommit()

Specified by:

beforeTransactionCommit in class AbstractTransactionImpl

doCommit

protected void doCommit()
                 throws TransactionException

Description copied from class: AbstractTransactionImpl

Perform the actual steps of committing a transaction according to the strategy.

Specified by:

doCommit in class AbstractTransactionImpl

Throws:

TransactionException - Indicates a problem committing the transaction

afterTransactionCompletion

protected void afterTransactionCompletion(int status)

Specified by:

afterTransactionCompletion in class AbstractTransactionImpl

afterAfterCompletion

protected void afterAfterCompletion()

Specified by:

afterAfterCompletion in class AbstractTransactionImpl

beforeTransactionRollBack

protected void beforeTransactionRollBack()

Specified by:

beforeTransactionRollBack in class AbstractTransactionImpl

doRollback

protected void doRollback()
                   throws TransactionException

Description copied from class: AbstractTransactionImpl

Perform the actual steps of rolling back a transaction according to the strategy.

Specified by:

doRollback in class AbstractTransactionImpl

Throws:

TransactionException - Indicates a problem rolling back the transaction

isInitiator

public boolean isInitiator()

Description copied from interface: Transaction

Is this transaction the initiator of any underlying transaction?

Returns:

true if this transaction initiated the underlying transaction; false otherwise.

createIsolationDelegate

public IsolationDelegate createIsolationDelegate()

Description copied from interface: TransactionImplementor

Retrieve an isolation delegate appropriate for this transaction strategy.

Returns:

An isolation delegate.

getJoinStatus

public JoinStatus getJoinStatus()

Description copied from interface: TransactionImplementor

Get the current state of this transaction's join status.

Returns:

The current join status

markRollbackOnly

public void markRollbackOnly()

Description copied from interface: TransactionImplementor

Make a best effort to mark the underlying transaction for rollback only.

join

public void join()

Description copied from interface: TransactionImplementor

Perform a join to the underlying transaction

Specified by:

join in interface TransactionImplementor

Overrides:

join in class AbstractTransactionImpl

resetJoinStatus

public void resetJoinStatus()

Description copied from interface: TransactionImplementor

Reset this transaction's join status.

Specified by:

resetJoinStatus in interface TransactionImplementor

Overrides:

resetJoinStatus in class AbstractTransactionImpl

isActive

public boolean isActive()
                 throws HibernateException

Description copied from interface: Transaction

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 Transaction

Overrides:

isActive in class AbstractTransactionImpl

Returns:

true if the transaction is still active; false otherwise.

Throws:

HibernateException - Indicates a problem checking the transaction status.
