Constructor Detail

JDBCTransactionFactory

public JDBCTransactionFactory()
Method Detail

getDefaultReleaseMode

public ConnectionReleaseMode getDefaultReleaseMode()
Get the default connection release mode.

Specified by:
getDefaultReleaseMode in interface TransactionFactory
Returns:
The default release mode associated with this strategy

createTransaction

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

configure

public void configure(Properties props)
               throws HibernateException
Configure from the given properties.

Specified by:
configure in interface TransactionFactory
Parameters:
props - The configuration properties.
Throws:
HibernateException - Indicates a problem configuring this factory.

isTransactionManagerRequired

public boolean isTransactionManagerRequired()
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()
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)
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.
