| org.hibernate.StatelessSession
All known Subclasses: org.hibernate.impl.StatelessSessionImpl,
| StatelessSession | | public interface StatelessSession extends Serializable(Code) | | A command-oriented API for performing bulk operations
against a database.
A stateless session does not implement a first-level cache nor
interact with any second-level cache, nor does it implement
transactional write-behind or automatic dirty checking, nor do
operations cascade to associated instances. Collections are
ignored by a stateless session. Operations performed via a
stateless session bypass Hibernate's event model and
interceptors. Stateless sessions are vulnerable to data
aliasing effects, due to the lack of a first-level cache.
For certain kinds of transactions, a stateless session may
perform slightly faster than a stateful session.

| Method Summary | |
| public Transaction | beginTransaction()
Begin a Hibernate transaction. | | public void | close()
Close the stateless session and release the JDBC connection. | | public Connection | connection()
Returns the current JDBC connection associated with this
instance.
If the session is using aggressive connection release (as in a
CMT environment), it is the application's responsibility to
close the connection returned by this call. | | public Criteria | createCriteria(Class persistentClass)
Create a new Criteria instance, for the given entity class,
or a superclass of an entity class. | | public Criteria | createCriteria(Class persistentClass, String alias)
Create a new Criteria instance, for the given entity class,
or a superclass of an entity class, with the given alias. | | public Criteria | createCriteria(String entityName)
Create a new Criteria instance, for the given entity name. | | public Criteria | createCriteria(String entityName, String alias)
Create a new Criteria instance, for the given entity name,
with the given alias. | | public Query | createQuery(String queryString)
Create a new instance of Query for the given HQL query string. | | public SQLQuery | createSQLQuery(String queryString)
Create a new instance of SQLQuery for the given SQL query string. | | public void | delete(Object entity)
Delete a row. | | public void | delete(String entityName, Object entity)
Delete a row. | | public Object | get(String entityName, Serializable id)
Retrieve a row. | | public Object | get(Class entityClass, Serializable id)
Retrieve a row. | | public Object | get(String entityName, Serializable id, LockMode lockMode)
Retrieve a row, obtaining the specified lock mode. | | public Object | get(Class entityClass, Serializable id, LockMode lockMode)
Retrieve a row, obtaining the specified lock mode. | | public Query | getNamedQuery(String queryName)
Obtain an instance of Query for a named query string defined in
the mapping file. | | public Transaction | getTransaction()
Get the current Hibernate transaction. | | public Serializable | insert(Object entity)
Insert a row. | | public Serializable | insert(String entityName, Object entity)
Insert a row. | | public void | refresh(Object entity)
Refresh the entity instance state from the database. | | public void | refresh(String entityName, Object entity)
Refresh the entity instance state from the database. | | public void | refresh(Object entity, LockMode lockMode)
Refresh the entity instance state from the database. | | public void | refresh(String entityName, Object entity, LockMode lockMode)
Refresh the entity instance state from the database. | | public void | update(Object entity)
Update a row. | | public void | update(String entityName, Object entity)
Update a row. |
| beginTransaction | | public Transaction beginTransaction()(Code) | | Begin a Hibernate transaction.
|
| close | | public void close()(Code) | | Close the stateless session and release the JDBC connection.
|
| connection | | public Connection connection()(Code) | | Returns the current JDBC connection associated with this
instance.
If the session is using aggressive connection release (as in a
CMT environment), it is the application's responsibility to
close the connection returned by this call. Otherwise, the
application should not close the connection.
