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()

Specified by:

close in interface EntityManager

isOpen

public boolean isOpen()

Specified by:

isOpen in interface EntityManager

createEntityGraph

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

Specified by:

createEntityGraph in interface EntityManager

createEntityGraph

public EntityGraph<?> createEntityGraph(String graphName)

Specified by:

createEntityGraph in interface EntityManager

getEntityGraph

public EntityGraph<?> getEntityGraph(String graphName)

Specified by:

getEntityGraph in interface EntityManager

getEntityGraphs

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

Specified by:

getEntityGraphs in interface EntityManager

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.
