All Implemented Interfaces:

ObjectPersister

@Deprecated
public class ReflectiveObjectPersister
extends AbstractObjectPersister
implements ObjectPersister

Deprecated.

since 7.17.0

Uses Hibernate metadata to persist imported objects. This code is a direct port of the old import code that was scattered between ReverseDatabinder and poorly factored helper classes. Hopefully, though, it is a lot easier to understand encapsulated here.

Limitations: the ReflectiveObjectPersister is NOT generic enough to persist anything you throw at it. It makes assumptions about the objects that are true of most Confluence hibernate objects: including the presence of an ID of type Long. Types that the reflective persister can not handle will need their own specific persister, for example PropertySetItemPersister.

persist

public List<TransientHibernateHandle> persist(ImportProcessorContext context,

                                       throws Exception

Description copied from interface: ObjectPersister

Persist a given imported object.

Specified by:

persist in interface ObjectPersister

Parameters:

context - the context of the current import operation

importedObject - the object to save.

Returns:

a list of handles of the objects that were saved. If IDs are being rewritten on import, this list should still contain the pre-rewriting ID as it appears in the backup file

Throws:

Exception - if something goes wrong. To avoid duplication of "wrap everything in one exception type" code in every persister, it is assumed wrapping happens at a higher level.

unproxyIfRequired

public static Object unproxyIfRequired(Object object)
                                throws org.hibernate.HibernateException

Deprecated.

When an object is retrieved from a Hibernate session, due to its lazy loading strategy, the object is possibly a proxy object. When net.sf.hibernate.metadata.ClassMetadata#setPropertyValue(Object target, String property, Object value) is called but the target object is a proxy object. Then, the new value cannot be persisted to database. This method aims to turn a proxy object to a real object so any update (if happens) can be persisted to database.

Parameters:

object - an object got from a Hibernate session, this object is either a real object or a proxy object.

Returns:

a real object of the input object

Throws:

org.hibernate.HibernateException
