HibernatePersistenceProvider

public HibernatePersistenceProvider()

Method Detail

proxyDelegate

public Object proxyDelegate(Object delegate)

Wrap the delegate Hibernate Session in a proxy that supports HQL EL interpolation and implements FullTextSession if Hibernate Search is available in the classpath.

Overrides:

proxyDelegate in class PersistenceProvider

setFlushModeManual

public void setFlushModeManual(javax.persistence.EntityManager entityManager)

Description copied from class: PersistenceProvider

Set the flush mode to manual-only flushing. Called when an atomic persistence context is required.

Overrides:

setFlushModeManual in class PersistenceProvider

isDirty

public boolean isDirty(javax.persistence.EntityManager entityManager)

Description copied from class: PersistenceProvider

Does the persistence context have unflushed changes? If it does not, persistence context replication can be optimized.

Overrides:

isDirty in class PersistenceProvider

Returns:

true to indicate that there are unflushed changes

getId

public Object getId(Object bean,
                    javax.persistence.EntityManager entityManager)

Description copied from class: PersistenceProvider

Get the value of the entity identifier attribute.

Overrides:

getId in class PersistenceProvider

Parameters:

bean - a managed entity instance

getVersion

public Object getVersion(Object bean,
                         javax.persistence.EntityManager entityManager)

Description copied from class: PersistenceProvider

Get the value of the entity version attribute.

Overrides:

getVersion in class PersistenceProvider

Parameters:

bean - a managed entity instance

checkVersion

public void checkVersion(Object bean,
                         javax.persistence.EntityManager entityManager,
                         Object oldVersion,
                         Object version)

Overrides:

checkVersion in class PersistenceProvider

enableFilter

public void enableFilter(Filter f,
                         javax.persistence.EntityManager entityManager)

Description copied from class: PersistenceProvider

Enable a Filter. This is here just especially for Hibernate, since we well know that other products don't have such cool features.

Overrides:

enableFilter in class PersistenceProvider

registerSynchronization

public boolean registerSynchronization(Synchronization sync,
                                       javax.persistence.EntityManager entityManager)

Register a Synchronization with the current transaction.

Overrides:

registerSynchronization in class PersistenceProvider

getRenderFlushMode

public FlushModeType getRenderFlushMode()

Description copied from class: PersistenceProvider

What flush policy should we use during the render response phase? We should not be changing data during the render, so we can optimize performance by choosing not to flush.

Overrides:

getRenderFlushMode in class PersistenceProvider

Returns:

COMMIT or MANUAL

public static void checkVersion(Object value,
                                org.hibernate.Session session,
