Interface UserCollectionType
public interface UserCollectionType
A custom type for mapping user-written classes that implement PersistentCollection
boolean | contains(Object collection, Object entity) - Optional operation.
|
Iterator | getElementsIterator(Object collection) - Return an iterator over the elements of this collection - the passed collection
instance may or may not be a wrapper
|
Object | indexOf(Object collection, Object entity) - Optional operation.
|
Object | instantiate(int anticipatedSize) - Instantiate an empty instance of the "underlying" collection (not a wrapper),
but with the given anticipated size (i.e.
|
PersistentCollection | instantiate(SessionImplementor session, CollectionPersister persister) - Instantiate an uninitialized instance of the collection wrapper
|
Object | replaceElements(Object original, Object target, CollectionPersister persister, Object owner, Map copyCache, SessionImplementor session) - Replace the elements of a collection with the elements of another collection
|
PersistentCollection | wrap(SessionImplementor session, Object collection) - Wrap an instance of a collection
|
contains
public boolean contains(Object collection,
Object entity)
Optional operation. Does the collection contain the entity instance?
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
indexOf
public Object indexOf(Object collection,
Object entity)
Optional operation. Return the index of the entity in the collection.
instantiate
public Object instantiate(int anticipatedSize)
Instantiate an empty instance of the "underlying" collection (not a wrapper),
but with the given anticipated size (i.e. accounting for initial size
and perhaps load factor).
anticipatedSize
- The anticipated size of the instaniated collection
after we are done populating it. Note, may be negative to indicate that
we not yet know anything about the anticipated size (i.e., when initializing
from a result set row by row).
