MapType

@Deprecated
public MapType(TypeFactory.TypeScope typeScope,
               String role,
               String propertyRef)

已过时。

Use the other constructor

MapType

public MapType(String role,
               String propertyRef)

方法详细资料

instantiate

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

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.

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.

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.

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.

instantiate

public Object instantiate(int anticipatedSize)

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:

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

返回:

A newly instantiated collection to be wrapped.

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.

抛出:

HibernateException

indexOf

public Object indexOf(Object collection,
                      Object element)

覆盖:

indexOf 在类中 CollectionType
