Constructor Detail

CMTTransactionFactory

public CMTTransactionFactory()

Method Detail

getDefaultReleaseMode

public ConnectionReleaseMode getDefaultReleaseMode()

Description copied from interface: TransactionFactory

Get the default connection release mode.

Specified by:

getDefaultReleaseMode in interface TransactionFactory

Returns:

The default release mode associated with this strategy

configure

public void configure(Properties props)
               throws HibernateException

Description copied from interface: TransactionFactory

Configure from the given properties.

Specified by:

configure in interface TransactionFactory

Parameters:

props - The configuration properties.

Throws:

HibernateException - Indicates a problem configuring this factory.

createTransaction

public Transaction createTransaction(JDBCContext jdbcContext,
                                     TransactionFactory.Context transactionContext)
                              throws HibernateException

Description copied from interface: TransactionFactory

Begin a transaction and return the associated Transaction instance.

Specified by:

createTransaction in interface TransactionFactory

Parameters:

jdbcContext - The jdbc context to which the transaction belongs

transactionContext - The contract regarding the context in which this transaction will operate.

Returns:

Transaction

Throws:

HibernateException - Indicates a problem generating a transaction instance

isTransactionManagerRequired

public boolean isTransactionManagerRequired()

Description copied from interface: TransactionFactory

Do we require access to the JTA TransactionManager for this strategy?

Specified by:

isTransactionManagerRequired in interface TransactionFactory

Returns:

True if this strategy requires access to the JTA TransactionManager; false otherwise.

areCallbacksLocalToHibernateTransactions

public boolean areCallbacksLocalToHibernateTransactions()

Description copied from interface: TransactionFactory

Are all transaction callbacks local to Hibernate Transactions? Or can the callbacks originate from some other source (e.g. a JTA Synchronization).

Specified by:

areCallbacksLocalToHibernateTransactions in interface TransactionFactory

Returns:

true if callbacks only ever originate from the Hibernate Transaction; false otherwise.

isTransactionInProgress

public boolean isTransactionInProgress(JDBCContext jdbcContext,
                                       TransactionFactory.Context transactionContext,
                                       Transaction transaction)

Description copied from interface: TransactionFactory

Determine whether an underlying transaction is in progress.

Mainly this is used in determining whether to register a synchronization as well as whether or not to circumvent auto flushing outside transactions.

Specified by:

isTransactionInProgress in interface TransactionFactory

Parameters:

jdbcContext - The JDBC context

transactionContext - The transaction context

transaction - The Hibernate transaction

Returns:

true if an underlying transaction is know to be in effect.
