Constructor Detail

MapType

public MapType(String role,
               String propertyRef,
               boolean isEmbeddedInXML)
Method Detail

instantiate

public PersistentCollection instantiate(SessionImplementor 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 class CollectionType
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 by nullSafeGet() methods. This is used to establish the class of an array of this type.

Returns:
Class

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 class CollectionType
Parameters:
collection - The collection to be iterated
Returns:
The iterator.

wrap

public PersistentCollection wrap(SessionImplementor 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 class CollectionType
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 class CollectionType
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,
                              SessionImplementor session)
                       throws HibernateException
Description copied from class: CollectionType
Replace the elements of a collection with the elements of another collection.

Overrides:
replaceElements in class CollectionType
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 merged
copyCache - 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 class CollectionType
