Creates Sessions. Usually an application has a single SessionFactory.
Threads servicing client requests obtain Sessions from the factory.
Implementors must be threadsafe.
SessionFactorys are immutable. The behaviour of a SessionFactory is
controlled by properties supplied at configuration time. These properties are defined
on Environment.

Method Summary | |
void |
close()
Destroy this SessionFactory and release all resources (caches, connection pools, etc). |
void |
evict(Class persistentClass)
Evict all entries from the second-level cache. |
void |
evict(Class persistentClass,
Serializable id)
Evict an entry from the second-level cache. |
void |
evictCollection(String roleName)
Evict all entries from the second-level cache. |
void |
evictCollection(String roleName,
Serializable id)
Evict an entry from the second-level cache. |
void |
evictEntity(String entityName)
Evict all entries from the second-level cache. |
void |
evictEntity(String entityName,
Serializable id)
Evict an entry from the second-level cache. |
void |
evictQueries()
Evict any query result sets cached in the default query cache region. |
void |

Map |
getAllClassMetadata()
Get all ClassMetadata as a Map from entityname String to metadata object |
Map |
getAllCollectionMetadata()
Get all CollectionMetadata as a Map from role name to metadata object |
ClassMetadata |
getClassMetadata(Class persistentClass)
Get the ClassMetadata associated with the given entity class |
ClassMetadata |
getClassMetadata(String entityName)
Get the ClassMetadata associated with the given entity name |
CollectionMetadata |
getCollectionMetadata(String roleName)
Get the CollectionMetadata associated with the named collection role |
Session |
getCurrentSession()
Obtains the current session, where "current" is maintained in relation to the current JTA transaction; if a Session is not already associated with the current JTA transaction, a new Session will be opened and it will be associated with that JTA transaction. |
Statistics |
getStatistics()
Get the statistics for this session factory |
boolean |
isClosed()
Was this SessionFactory already closed? |
Session |
openSession()
Create database connection and open a Session on it. |
Session |
openSession(Connection connection)
Open a Session on the given connection. |
Session |
openSession(Connection connection,
Interceptor interceptor)
Open a Session on the given connection, specifying an interceptor. |
Session |
openSession(Interceptor interceptor)
Create database connection and open a Session on it, specifying an interceptor. |

Method Detail |
public Session openSession(Connection connection)
Note that the second-level cache will be disabled if you supply a JDBC connection. Hibernate will not be able to track any statements you might have executed in the same transaction. Consider implementing your own ConnectionProvider.
connection
- a connection provided by the application.
public Session openSession(Interceptor interceptor) throws HibernateException
interceptor
- a session-scoped interceptor
HibernateException
public Session openSession(Connection connection, Interceptor interceptor)
Note that the second-level cache will be disabled if you supply a JDBC connection. Hibernate will not be able to track any statements you might have executed in the same transaction. Consider implementing your own ConnectionProvider.
connection
- a connection provided by the application.interceptor
- a session-scoped interceptor

TransactionManager
for the given environment.
A Transaction
must also already be in effect
prior to calls to this method. If either condition fails, an exception
is thrown.
The Sessions returned from this method are automatically configured with
both the auto-flush
and
auto-close
attributes set to
true, meaning that the Session will be automatically flushed and closed
as part of the lifecycle for the JTA transaction to which it is associated.
