instantiate
public PersistentCollection instantiate(SharedSessionContractImplementor session, CollectionPersister persister, Serializable key)
Description copied from class:CollectionType
Instantiate an uninitialized collection wrapper or holder. Callers MUST add the holder to the persistence context!- Specified by:
instantiate
in classCollectionType
- Parameters:
session
- The session from which the request is originating.persister
- The underlying collection persister (metadata)key
- The owner key.- Returns:
- The instantiated collection.
-
getReturnedClass
public Class getReturnedClass()
Description copied from interface:Type
The class returned byType.nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.Object)
methods. This is used to establish the class of an array of this type.- Returns:
- The java type class handled by this type.
-
getElementsIterator
public Iterator getElementsIterator(Object collection)
Description copied from class:CollectionType
Get an iterator over the element set of the collection in POJO mode- Overrides:
getElementsIterator
in classCollectionType
- Parameters:
collection
- The collection to be iterated- Returns:
- The iterator.
-
wrap
public PersistentCollection wrap(SharedSessionContractImplementor session, Object collection)
Description copied from class:CollectionType
Wrap the naked collection instance in a wrapper, or instantiate a holder. Callers MUST add the holder to the persistence context!- Specified by:
wrap
in classCollectionType
- Parameters:
session
- The session from which the request is originating.collection
- The bare collection to be wrapped.- Returns:
- The wrapped collection.
-
instantiate
public Object instantiate(int anticipatedSize)
Description copied from class:CollectionType
Instantiate an empty instance of the "underlying" collection (not a wrapper), but with the given anticipated size (i.e. accounting for initial capacity and perhaps load factor).- Specified by:
instantiate
in classCollectionType
- Parameters:
anticipatedSize
- The anticipated size of the instaniated collection after we are done populating it.- Returns:
- A newly instantiated collection to be wrapped.
-
replaceElements
public Object replaceElements(Object original, Object target, Object owner, Map copyCache, SharedSessionContractImplementor session) throws HibernateException
Description copied from class:CollectionType
Replace the elements of a collection with the elements of another collection.- Overrides:
replaceElements
in classCollectionType
- Parameters:
original
- The 'source' of the replacement elements (where we copy from)target
- The target of the replacement elements (where we copy to)owner
- The owner of the collection being mergedcopyCache
- The map of elements already replaced.session
- The session from which the merge event originated.- Returns:
- The merged collection.
- Throws:
HibernateException
-
indexOf
public Object indexOf(Object collection, Object element)
- Overrides:
indexOf
in classCollectionType
