EntityManagerImpl

public EntityManagerImpl(EntityManagerFactoryImpl entityManagerFactory,
                         PersistenceContextType pcType,
                         SynchronizationType synchronizationType,

Method Detail

checkOpen

protected void checkOpen()

Specified by:

checkOpen in class AbstractEntityManagerImpl

checkOpen

public void checkOpen(boolean markForRollbackIfClosed)

Description copied from interface: HibernateEntityManagerImplementor

Used to ensure the EntityManager is open, throwing IllegalStateException if it is closed. Depending on the value of markForRollbackIfClosed, may also rollback any enlisted-in transaction. This distinction is made across various sections of the spec. Most failed checks should rollback. Section 3.10.7 (per 2.1 spec) lists cases related to calls on related query objects that should not rollback.

Specified by:

checkOpen in interface HibernateEntityManagerImplementor

Parameters:

markForRollbackIfClosed - If the EM is closed, should the transaction (if one) be marked for rollback?

getSession

public Session getSession()

Description copied from class: AbstractEntityManagerImpl

return a Session

Specified by:

getSession in interface HibernateEntityManager

Specified by:

getSession in class AbstractEntityManagerImpl

Returns:

The session

getRawSession

protected Session getRawSession()

Description copied from class: AbstractEntityManagerImpl

Return a Session (even if the entity manager is closed).

Specified by:

getRawSession in class AbstractEntityManagerImpl

Returns:

A session.

internalGetSession

protected Session internalGetSession()

Description copied from class: AbstractEntityManagerImpl

Return a Session without any validation checks.

Specified by:

internalGetSession in class AbstractEntityManagerImpl

Returns:

A session.

close

public void close()

Description copied from interface: EntityManager

Close an application-managed entity manager. After the close method has been invoked, all methods on the EntityManager instance and any Query and TypedQuery objects obtained from it will throw the IllegalStateException except for getProperties, getTransaction, and isOpen (which will return false). If this method is called when the entity manager is associated with an active transaction, the persistence context remains managed until the transaction completes.

Specified by:

close in interface EntityManager

isOpen

public boolean isOpen()

Description copied from interface: EntityManager

Determine whether the entity manager is open.

Specified by:

isOpen in interface EntityManager

Returns:

true until the entity manager has been closed

createEntityGraph

public <T> EntityGraph<T> createEntityGraph(Class<T> rootType)

Description copied from interface: EntityManager

Return a mutable EntityGraph that can be used to dynamically create an EntityGraph.

Specified by:

createEntityGraph in interface EntityManager

Parameters:

rootType - class of entity graph

Returns:

entity graph

createEntityGraph

public EntityGraph<?> createEntityGraph(String graphName)

Description copied from interface: EntityManager

Return a mutable copy of the named EntityGraph. If there is no entity graph with the specified name, null is returned.

Specified by:

createEntityGraph in interface EntityManager

Parameters:

graphName - name of an entity graph

Returns:

entity graph

getEntityGraph

public EntityGraph<?> getEntityGraph(String graphName)

Description copied from interface: EntityManager

Return a named EntityGraph. The returned EntityGraph should be considered immutable.

Specified by:

getEntityGraph in interface EntityManager

Parameters:

graphName - name of an existing entity graph

Returns:

named entity graph

getEntityGraphs

public <T> List<EntityGraph<? super T>> getEntityGraphs(Class<T> entityClass)

Description copied from interface: EntityManager

Return all named EntityGraphs that have been defined for the provided class type.

Specified by:

getEntityGraphs in interface EntityManager

Parameters:

entityClass - entity class

Returns:

list of all entity graphs defined for the entity

shouldAutoCloseSession

public boolean shouldAutoCloseSession()

Description copied from interface: SessionOwner

Should session automatically be closed after transaction completion?

Specified by:

shouldAutoCloseSession in interface SessionOwner

Returns:

true/false appropriately.

getExceptionMapper

public ExceptionMapper getExceptionMapper()

Specified by:

getExceptionMapper in interface SessionOwner

getAfterCompletionAction

public AfterCompletionAction getAfterCompletionAction()

Specified by:

getAfterCompletionAction in interface SessionOwner

getManagedFlushChecker

public ManagedFlushChecker getManagedFlushChecker()

Specified by:

getManagedFlushChecker in interface SessionOwner
