CustomCollectionType

@Deprecated
public CustomCollectionType(TypeFactory.TypeScope typeScope,
                            Class userTypeClass,
                            String role,

已过时。

Use the other constructor

CustomCollectionType

public CustomCollectionType(Class userTypeClass,
                            String role,
                            String foreignKeyPropertyName)

instantiate

public PersistentCollection instantiate(SharedSessionContractImplementor session,
                                        CollectionPersister persister,
                                        Serializable key)
                                 throws HibernateException

从类复制的说明: CollectionType

Instantiate an uninitialized collection wrapper or holder. Callers MUST add the holder to the persistence context!

指定者:

instantiate 在类中 CollectionType

参数:

session - The session from which the request is originating.

persister - The underlying collection persister (metadata)

key - The owner key.

返回:

The instantiated collection.

抛出:

HibernateException

wrap

public PersistentCollection wrap(SharedSessionContractImplementor session,
                                 Object collection)

从类复制的说明: CollectionType

Wrap the naked collection instance in a wrapper, or instantiate a holder. Callers MUST add the holder to the persistence context!

指定者:

wrap 在类中 CollectionType

参数:

session - The session from which the request is originating.

collection - The bare collection to be wrapped.

返回:

The wrapped collection.

getReturnedClass

public Class getReturnedClass()

从接口复制的说明: 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.

返回:

The java type class handled by this type.

instantiate

public Object instantiate(int anticipatedType)

从类复制的说明: 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).

指定者:

instantiate 在类中 CollectionType

参数:

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

返回:

A newly instantiated collection to be wrapped.

getElementsIterator

public Iterator getElementsIterator(Object collection)

从类复制的说明: CollectionType

Get an iterator over the element set of the collection in POJO mode

覆盖:

getElementsIterator 在类中 CollectionType

参数:

collection - The collection to be iterated

返回:

The iterator.

contains

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

覆盖:

contains 在类中 CollectionType

indexOf

public Object indexOf(Object collection,
                      Object entity)

覆盖:

indexOf 在类中 CollectionType

replaceElements

public Object replaceElements(Object original,
                              Object target,
                              Object owner,
                              Map copyCache,
                              SharedSessionContractImplementor session)
                       throws HibernateException

从类复制的说明: CollectionType

Replace the elements of a collection with the elements of another collection.

覆盖:

replaceElements 在类中 CollectionType

参数:

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.

返回:

The merged collection.
