Method Detail

instantiate

public PersistentCollection instantiate(SessionImplementor session,
                                        CollectionPersister persister)
                                 throws HibernateException

Instantiate an uninitialized instance of the collection wrapper

Throws:

HibernateException

wrap

public PersistentCollection wrap(SessionImplementor session,
                                 Object collection)

Wrap an instance of a collection

getElementsIterator

public Iterator getElementsIterator(Object collection)

Return an iterator over the elements of this collection - the passed collection instance may or may not be a wrapper

contains

public boolean contains(Object collection,
                        Object entity)

Optional operation. Does the collection contain the entity instance?

indexOf

public Object indexOf(Object collection,
                      Object entity)

Optional operation. Return the index of the entity in the collection.

replaceElements

public Object replaceElements(Object original,
                              Object target,
                              CollectionPersister persister,
                              Object owner,
                              Map copyCache,
                              SessionImplementor session)
                       throws HibernateException

Replace the elements of a collection with the elements of another collection

Throws:

HibernateException

instantiate

public Object instantiate()

Instantiate an empty instance of the "underlying" collection (not a wrapper)
