Method Detail

createSession

public static Session createSession()

Creates a new hibernate session.

releaseSession

public static void releaseSession()

When a client does not require a hibernate session any longer, it should release the session by calling this operation.

getSession

public static Session getSession()

Get the current session for your thread. When a session is started, it is also associated with the current thread (see createSession()). This operation allows for convenient access to the current session. For example from inside a business facade, when the session itself was created transparently by an aspect of that business facade.

createQuery

public static Query createQuery(java.lang.String hql)

Convenience method to allow you to create a query without requesting the hibernate session.

createCriteria

public static Criteria createCriteria(java.lang.Class queryClass)

Convenience method to allow you to create a criteria query without requesting the hibernate session.

isStarted

public static boolean isStarted()

Is hibernate allready started or not ?

Returns:

getSessionFactory

public static org.hibernate.SessionFactory getSessionFactory()

Returns:

the SessionFactory in the system. Handy for getting to meta data, for example.

getAll

public static java.util.List getAll(java.lang.Class clazz)

This is a generic operation for retrieving all instances of a certain type of domain model class.. Just supply the Class that indicates the model bean of interest, and you get back a list of all objects of that type in the system. It also works on PersistentEnums.

Parameters:

clazz - the type of object to look for.

Returns:

a list of all objects of the requested type.

getHibernateConfig

public static org.hibernate.cfg.Configuration getHibernateConfig()

Returns the hibernate Configuration object. This an objectified version of all your mapping files (hbm.xml). This method now also supports the use of an AnnotationConfiguration-object (available as of Hibernate 3.2). This is an expanded Configuration-object allowing the use of EJB3 annotations and the accompanying Hibernate 3.2 annotation extensions. The method automatically determines which version to use depending on the existence of a hibernate.cfg.xml-file. In that case the more powerful AnnotationConfiguration is used. Bear in mind that even in this case, regular usage of the classic hbm.xml mapping files is still allowed. You merely have the option to mix and match annotations and mapping files or go completely with annotations (for more information see the Hibernate 3.2 documentation).

initialize

public static void initialize(java.lang.Object proxy)

Swizzles in the given hibernate proxy.

clearCache

public static void clearCache()

This operation clears the entire second level cache, as well as the query cache of hibernate. It is primarily intended to be used in the unit testing to avoid interference between test cases...

getEnumFromInt

public static java.lang.Object getEnumFromInt(int id,
                                              java.lang.Class type)

delete

public static void delete(Entity entity)

Register an entity for deletion

Parameters:

entity -

create

public static java.lang.Object create(java.lang.Class clazz)

Factory method for creating new entities. Create an instance of the given class, which will be registered for save in the autosync session.

Parameters:

clazz -

Returns:

autoSync

public static void autoSync(java.util.Collection entities)
                     throws org.hibernate.ObjectDeletedException

Throws:

org.hibernate.ObjectDeletedException

autoSync

public static void autoSync(Entity entity)
                     throws org.hibernate.ObjectDeletedException
