                      throws HibernateException

cascade the action to the child object

Throws:

HibernateException

getCascadableChildrenIterator

public abstract Iterator getCascadableChildrenIterator(EventSource session,
                                                       CollectionType collectionType,
                                                       Object collection)

Should this action be cascaded to the given (possibly uninitialized) collection?

deleteOrphans

public abstract boolean deleteOrphans()

Do we need to handle orphan delete for this action?

getLoadedElementsIterator

public static Iterator getLoadedElementsIterator(SessionImplementor session,
                                                 CollectionType collectionType,
                                                 Object collection)

Iterate just the elements of the collection that are already there. Don't load any new elements from the database.
