| CollectionPersister |
The CollectionPersister is responsible for persisting collections of embedded
or referenced documents. When a PersistentCollection is scheduledForDeletion
in the UnitOfWork by calling PersistentCollection::clear() or is
de-referenced in the domain application code, CollectionPersister::delete()
will be called. When documents within the PersistentCollection are added or
removed, CollectionPersister::update() will be called, which may set the
entire collection or delete/insert individual elements, depending on the
mapping strategy. |
