Method Detail

instantiate

public PersistentCollection instantiate(SharedSessionContractImplementor session,
                                        CollectionPersister persister,
                                        Serializable 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

getReturnedClass

public Class getReturnedClass()

Description copied from interface: Type

The class returned by Type.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.

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 <b>MUST</b> 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.
