Method Detail

initialize

public static void initialize(Object proxy)
                       throws HibernateException

Force initialization of a proxy or persistent collection.

Note: This only ensures intialization of a proxy object or collection; it is not guaranteed that the elements INSIDE the collection will be initialized/materialized.

Parameters:

proxy - a persistable object, proxy, persistent collection or null

Throws:

HibernateException - if we can't initialize the proxy at this time, eg. the Session was closed

isInitialized

public static boolean isInitialized(Object proxy)

Check if the proxy or persistent collection is initialized.

Parameters:

proxy - a persistable object, proxy, persistent collection or null

Returns:

true if the argument is already initialized, or is not a proxy or collection

getClass

public static Class getClass(Object proxy)

Get the true, underlying class of a proxied persistent class. This operation will initialize a proxy by side-effect.

Parameters:

proxy - a persistable object or proxy

Returns:

the true class of the instance

Throws:

HibernateException

getLobCreator

public static LobCreator getLobCreator(Session session)

getLobCreator

public static LobCreator getLobCreator(SessionImplementor session)

close

public static void close(Iterator iterator)
                  throws HibernateException

Close an Iterator created by iterate() immediately, instead of waiting until the session is closed or disconnected.

Parameters:

iterator - an Iterator created by iterate()

Throws:

HibernateException

isPropertyInitialized

public static boolean isPropertyInitialized(Object proxy,
                            String propertyName)

Check if the property is initialized. If the named property does not exist or is not persistent, this method always returns true.

Parameters:

proxy - The potential proxy

propertyName - the name of a persistent attribute of the object

Returns:

true if the named property of the object is not listed as uninitialized; false otherwise
