CustomCollectionType

public CustomCollectionType(ManagedBean<? extends UserCollectionType> userTypeBean,
 String role,
 String foreignKeyPropertyName)

Method Details

getReturnedClass

public Class<?> getReturnedClass()

Description copied from interface: Type

The class handled by this type.

Returns:

The Java class handled by this type.

getCollectionClassification

public CollectionClassification getCollectionClassification()

Specified by:

getCollectionClassification in class CollectionType

instantiate

public PersistentCollection<?> instantiate(SharedSessionContractImplementor session,
 CollectionPersister persister,
 Object key)
                                    throws HibernateException

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.

Throws:

HibernateException

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 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 anticipatedType)

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:

anticipatedType - The anticipated size of the instantiated collection after we are done populating it.

Returns:

A newly instantiated collection to be wrapped.

getElementsIterator

public Iterator<?> getElementsIterator(Object collection)

Description copied from class: CollectionType

Get an iterator over the element set of the collection, which may not yet be wrapped

Overrides:

getElementsIterator in class CollectionType

Parameters:

collection - The collection to be iterated

Returns:

The element iterator

contains

public boolean contains(Object collection,
 Object entity,
 SharedSessionContractImplementor session)

Overrides:

contains in class CollectionType

indexOf

public Object indexOf(Object collection,
 Object entity)

Overrides:

indexOf in class CollectionType

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 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

renderLoggableString

protected String renderLoggableString(Object value,
 SessionFactoryImplementor factory)
                               throws HibernateException

Overrides:

renderLoggableString in class CollectionType

Throws:

HibernateException

getUserType

public UserCollectionType getUserType()
