Method Summary

Methods

Modifier and Type	Method and Description
boolean	canBeDriver() Can the transactions created from this strategy act as the driver? In other words can the user actually manage transactions with this strategy?
boolean	compatibleWithJtaSynchronization() Should we attempt to register JTA transaction synchronizations.
T	createTransaction(TransactionCoordinator coordinator) Construct a transaction instance compatible with this strategy.
ConnectionReleaseMode	getDefaultReleaseMode() Get the default connection release mode.
boolean	isJoinableJtaTransaction(TransactionCoordinator transactionCoordinator, T transaction) Can the underlying transaction represented by the passed Hibernate TransactionImplementor be joined?

Method Detail

createTransaction

T createTransaction(TransactionCoordinator coordinator)

Construct a transaction instance compatible with this strategy.

Parameters:

coordinator - The coordinator for this transaction

Returns:

The appropriate transaction instance.

Throws:

HibernateException - Indicates a problem constructing the transaction.

canBeDriver

boolean canBeDriver()

Can the transactions created from this strategy act as the driver? In other words can the user actually manage transactions with this strategy?

Returns:

true if the transaction strategy represented by this factory can act as the driver callback; false otherwise.

compatibleWithJtaSynchronization

boolean compatibleWithJtaSynchronization()

Should we attempt to register JTA transaction synchronizations.

In other words, is this strategy JTA-based?

Returns:

true if the transaction strategy represented by this factory is compatible with registering synchronizations; false otherwise.

isJoinableJtaTransaction

boolean isJoinableJtaTransaction(TransactionCoordinator transactionCoordinator,
                               T transaction)

Can the underlying transaction represented by the passed Hibernate TransactionImplementor be joined?

Parameters:

transactionCoordinator - The transaction coordinator

transaction - The current Hibernate transaction

Returns:

true is the transaction can be joined; false otherwise.

getDefaultReleaseMode

ConnectionReleaseMode getDefaultReleaseMode()

Get the default connection release mode.

Returns:

The default release mode associated with this strategy
