                 Class elementClass)

方法详细资料

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 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

getElementsIterator

public Iterator getElementsIterator(Object collection)

Not defined for collections of primitive type

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 array)

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.

array - The bare collection to be wrapped.

返回:

The wrapped collection.

isArrayType

public boolean isArrayType()

覆盖:

isArrayType 在类中 CollectionType

toLoggableString

public String toLoggableString(Object value,
                               SessionFactoryImplementor factory)
                        throws HibernateException

从接口复制的说明: Type

Generate a representation of the value for logging purposes.

指定者:

toLoggableString 在接口中 Type

覆盖:

toLoggableString 在类中 CollectionType

参数:

value - The value to be logged

factory - The session factory

返回:

The loggable representation

抛出:

HibernateException - An error from Hibernate

instantiateResult

public Object instantiateResult(Object original)

从类复制的说明: CollectionType

Instantiate a new "underlying" collection exhibiting the same capacity characteristics and the passed "original".

覆盖:

instantiateResult 在类中 CollectionType

参数:

original - The original collection.

返回:

The newly instantiated collection.

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.

返回:

The merged collection.

instantiate

public Object instantiate(int anticipatedSize)
