Constructor Detail

StatelessSessionImpl

public StatelessSessionImpl(SessionFactoryImpl factory,
                            SessionCreationOptions options)

Method Detail

shouldAutoJoinTransaction

public boolean shouldAutoJoinTransaction()

Description copied from interface: TransactionCoordinatorBuilder.Options

Indicates whether an active transaction should be automatically joined. Only relevant for JTA-based TransactionCoordinator instances.

Specified by:

shouldAutoJoinTransaction in interface TransactionCoordinatorBuilder.Options

Overrides:

shouldAutoJoinTransaction in class AbstractSharedSessionContract

Returns:

true indicates the active transaction should be auto joined; false indicates it should not (until TransactionCoordinator.explicitJoin() is called).

insert

public Object insert(Object entity)

Description copied from interface: StatelessSession

Insert a record.

If the entity @Id field is declared to be generated, for example, if it is annotated @GeneratedId, the id is generated and assigned to the given instance.

The PostPersist callback will be triggered if the operation is successful.

Specified by:

insert in interface StatelessSession

Parameters:

entity - a new transient instance

Returns:

The identifier of the inserted entity

insert

public Object insert(String entityName,
                     Object entity)

Description copied from interface: StatelessSession

Insert a record.

The PostPersist callback will be triggered if the operation is successful.

Specified by:

insert in interface StatelessSession

Parameters:

entityName - The entityName for the entity to be inserted

entity - a new transient instance

Returns:

the identifier of the instance

delete

public void delete(Object entity)

Description copied from interface: StatelessSession

Delete a record.

The PostRemove callback will be triggered if the operation is successful.

Specified by:

delete in interface StatelessSession

Parameters:

entity - a detached entity instance

delete

public void delete(String entityName,
                   Object entity)

Description copied from interface: StatelessSession

Delete a record.

The PostRemove callback will be triggered if the operation is successful.

Specified by:

delete in interface StatelessSession

Parameters:

entityName - The entityName for the entity to be deleted

entity - a detached entity instance

update

public void update(Object entity)

Description copied from interface: StatelessSession

Update a record.

The PostUpdate callback will be triggered if the operation is successful.

Specified by:

update in interface StatelessSession

Parameters:

entity - a detached entity instance

upsert

public void upsert(Object entity)

Description copied from interface: StatelessSession

Use a SQL merge into statement to perform an upsert, that is, to insert the record if it does not exist, or update it if it already exists.

This method never performs id generation, and does not accept an entity instance with a null identifier. When id generation is required, use StatelessSession.insert(Object).

On the other hand, upsert() does accept an entity instance with an assigned identifier value, even if the entity @Id field is declared to be generated, for example, if it is annotated @GeneratedId. Thus, this method may be used to import data from an external source.

Specified by:

upsert in interface StatelessSession

Parameters:

entity - a detached entity instance, or a new instance with an assigned identifier

update

public void update(String entityName,
                   Object entity)

Parameters:

entityName - The entityName for the entity to be updated

Specified by:

immediateLoad in interface SharedSessionContractImplementor

Throws:

HibernateException

initializeCollection

public void initializeCollection(PersistentCollection<?> collection,
                                 boolean writing)
                          throws HibernateException

Description copied from interface: SharedSessionContractImplementor

Initialize the given collection (if not already initialized).

Specified by:

initializeCollection in interface SharedSessionContractImplementor

Throws:

HibernateException

instantiate

public Object instantiate(String entityName,
                          Object id)
                   throws HibernateException

Description copied from interface: SharedSessionContractImplementor

Instantiate the entity class, initializing with the given identifier.

Specified by:

instantiate in interface SharedSessionContractImplementor

Throws:

HibernateException

instantiate

public Object instantiate(EntityPersister persister,
                          Object id)
                   throws HibernateException

Description copied from interface: SharedSessionContractImplementor

Instantiate the entity class of the given EntityPersister, initializing the new instance with the given identifier.

This is more efficient than SharedSessionContractImplementor.instantiate(String, Object), but not always interchangeable, since a single persister might be responsible for multiple types.

Specified by:

instantiate in interface SharedSessionContractImplementor

Throws:

HibernateException

internalLoad

public Object internalLoad(String entityName,
                           Object id,
                           boolean eager,
                           boolean nullable)
                    throws HibernateException

Description copied from interface: SharedSessionContractImplementor

Obtain an entity instance with the given id, without checking if it was deleted or scheduled for deletion.

• When nullable = false, this method may create a new proxy or return an existing proxy; if it does not exist, an exception is thrown.
• When nullable = true, the method does not create new proxies, though it might return an existing proxy; if it does not exist, a null value is returned.

When eager = true, the object is eagerly fetched from the database.

Specified by:

internalLoad in interface SharedSessionContractImplementor

Throws:

HibernateException

fetch

public void fetch(Object association)

Description copied from interface: StatelessSession

Fetch an association or collection that's configured for lazy loading.

 Book book = session.get(Book.class, isbn);  // book is immediately detached
 session.fetch(book.getAuthors());           // fetch the associated authors
 book.getAuthors().forEach(author -> ... );  // iterate the collection
 

Warning: this operation in a stateless session is quite sensitive to data aliasing effects and should be used with great care. It's usually better to fetch associations using eager join fetching.

Specified by:

fetch in interface StatelessSession

Parameters:

association - a lazy-loaded association

See Also:

Hibernate.initialize(Object)

getIdentifier

public Object getIdentifier(Object entity)
                     throws HibernateException

getCacheMode

public CacheMode getCacheMode()

Description copied from interface: SharedSessionContractImplementor

Get the current CacheMode for this session.

Description copied from interface: SharedSessionContractImplementor

Set the current FlushMode for this session.

The flush mode determines the points at which the session is flushed. Flushing is the process of synchronizing the underlying persistent store with persistable state held in memory.

For a logically "read-only" session, it's reasonable to set the session flush mode to FlushMode.MANUAL at the start of the session (in order skip some work and gain some extra performance).
