@Incubating
public interface LazyInitializable

The most general abstraction over collections which may be fetched lazily.

• Hibernate core "wraps" a Java collection in an instance of PersistentCollection.
• Similarly, Envers uses its own custom collection wrappers: ListProxy, SetProxy, and friends).

All of these wrapper objects extend LazyInitializable, allowing:

• the method Hibernate.isInitialized(Object) to determine if the collection was already fetched, and
• the method Hibernate.initialize(Object) to force it to be fetched.
