方法概要

修饰符和类型	方法	说明
boolean	afterInsert(SharedSessionContractImplementor session, Object key, Object value)	Called afterQuery an item has been inserted (afterQuery the transaction completes), instead of calling release().
boolean	afterUpdate(SharedSessionContractImplementor session, Object key, Object value, SoftLock lock)	Called afterQuery an item has been updated (afterQuery the transaction completes), instead of calling release().
Object	generateCacheKey(Object[] naturalIdValues, EntityPersister rootEntityDescriptor, SharedSessionContractImplementor session)	To create instances of NaturalIdCacheKey for this region, Hibernate will invoke this method exclusively so that generated implementations can generate optimised keys.
protected AccessedDataClassification	getAccessedDataClassification()
AccessType	getAccessType()	The type of access implemented
Object[]	getNaturalIdValues(Object cacheKey)	Performs reverse operation to NaturalIdDataAccess.generateCacheKey(java.lang.Object[], org.hibernate.persister.entity.EntityPersister, org.hibernate.engine.spi.SharedSessionContractImplementor), returning the original naturalIdValues.
protected Comparator	getVersionComparator()
boolean	insert(SharedSessionContractImplementor session, Object key, Object value)	Called afterQuery an item has been inserted (beforeQuery the transaction completes), instead of calling evict().
boolean	update(SharedSessionContractImplementor session, Object key, Object value)	Called afterQuery an item has been updated (beforeQuery the transaction completes), instead of calling evict().

NaturalIdReadWriteAccess

public NaturalIdReadWriteAccess(DomainDataRegion region,
                                CacheKeysFactory keysFactory,
                                DomainDataStorageAccess storageAccess,
                                NaturalIdDataCachingConfig naturalIdDataCachingConfig)

方法详细资料

getAccessedDataClassification

protected AccessedDataClassification getAccessedDataClassification()

指定者:

getAccessedDataClassification 在类中 AbstractReadWriteAccess

getAccessType

public AccessType getAccessType()

从接口复制的说明: CachedDomainDataAccess

The type of access implemented

指定者:

getAccessType 在接口中 CachedDomainDataAccess

getVersionComparator

protected Comparator getVersionComparator()

指定者:

getVersionComparator 在类中 AbstractReadWriteAccess

generateCacheKey

public Object generateCacheKey(Object[] naturalIdValues,
                               EntityPersister rootEntityDescriptor,
                               SharedSessionContractImplementor session)

从接口复制的说明: NaturalIdDataAccess

To create instances of NaturalIdCacheKey for this region, Hibernate will invoke this method exclusively so that generated implementations can generate optimised keys.

指定者:

generateCacheKey 在接口中 NaturalIdDataAccess

参数:

naturalIdValues - the sequence of values which unequivocally identifies a cached element on this region

rootEntityDescriptor - the persister of the element being cached

返回:

a key which can be used to identify an element unequivocally on this same region

getNaturalIdValues

public Object[] getNaturalIdValues(Object cacheKey)

从接口复制的说明: NaturalIdDataAccess

Performs reverse operation to NaturalIdDataAccess.generateCacheKey(java.lang.Object[], org.hibernate.persister.entity.EntityPersister, org.hibernate.engine.spi.SharedSessionContractImplementor), returning the original naturalIdValues.

指定者:

getNaturalIdValues 在接口中 NaturalIdDataAccess

参数:

cacheKey - key returned from NaturalIdDataAccess.generateCacheKey(java.lang.Object[], org.hibernate.persister.entity.EntityPersister, org.hibernate.engine.spi.SharedSessionContractImplementor)

返回:

the sequence of values which unequivocally identifies a cached element on this region

insert

public boolean insert(SharedSessionContractImplementor session,
                      Object key,
                      Object value)

从接口复制的说明: NaturalIdDataAccess

Called afterQuery an item has been inserted (beforeQuery the transaction completes), instead of calling evict(). This method is used by "synchronous" concurrency strategies.

指定者:

insert 在接口中 NaturalIdDataAccess

参数:

session - Current session

key - The item key

value - The item

返回:

Were the contents of the cache actually changed by this operation?

afterInsert

public boolean afterInsert(SharedSessionContractImplementor session,
                           Object key,
                           Object value)

从接口复制的说明: NaturalIdDataAccess

Called afterQuery an item has been inserted (afterQuery the transaction completes), instead of calling release(). This method is used by "asynchronous" concurrency strategies.

指定者:

afterInsert 在接口中 NaturalIdDataAccess

参数:

session - Current session

key - The item key

value - The item

返回:

Were the contents of the cache actually changed by this operation?

update

public boolean update(SharedSessionContractImplementor session,
                      Object key,
                      Object value)

从接口复制的说明: NaturalIdDataAccess

Called afterQuery an item has been updated (beforeQuery the transaction completes), instead of calling evict(). This method is used by "synchronous" concurrency strategies.

指定者:

update 在接口中 NaturalIdDataAccess

参数:

session - Current session

key - The item key

value - The item

返回:

Were the contents of the cache actually changed by this operation?

afterUpdate

public boolean afterUpdate(SharedSessionContractImplementor session,
                           Object key,
                           Object value,
                           SoftLock lock)

从接口复制的说明: NaturalIdDataAccess

Called afterQuery an item has been updated (afterQuery the transaction completes), instead of calling release(). This method is used by "asynchronous" concurrency strategies.

指定者:

afterUpdate 在接口中 NaturalIdDataAccess

参数:

session - Current session

key - The item key

value - The item

lock - The lock previously obtained from CachedDomainDataAccess.lockItem(org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.Object, java.lang.Object)

返回:

Were the contents of the cache actually changed by this operation?
