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 persister, SharedSessionContractImplementor session)	To create instances of NaturalIdCacheKey for this region, Hibernate will invoke this method exclusively so that generated implementations can generate optimised keys.
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.
boolean	insert(SharedSessionContractImplementor session, Object key, Object value)	Called afterQuery an item has been inserted (beforeQuery the transaction completes), instead of calling evict().
SoftLock	lockItem(SharedSessionContractImplementor session, Object key, Object version)	We are going to attempt to update/delete the keyed object.
SoftLock	lockRegion()	Lock the entire region
void	unlockItem(SharedSessionContractImplementor session, Object key, SoftLock lock)	Called when we have finished the attempted update/delete (which may or may not have been successful), after transaction completion.
void	unlockRegion(SoftLock lock)	Called after we have finished the attempted invalidation of the entire region

AbstractNaturalIdDataAccess

public AbstractNaturalIdDataAccess(DomainDataRegion region,
                                   CacheKeysFactory keysFactory,
                                   DomainDataStorageAccess storageAccess,
                                   NaturalIdDataCachingConfig config)

方法详细资料

generateCacheKey

public Object generateCacheKey(Object[] naturalIdValues,
                               EntityPersister persister,
                               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

persister - 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?

lockRegion

public SoftLock lockRegion()

从接口复制的说明: CachedDomainDataAccess

Lock the entire region

指定者:

lockRegion 在接口中 CachedDomainDataAccess

覆盖:

lockRegion 在类中 AbstractCachedDomainDataAccess

返回:

A representation of our lock on the item; or null.

unlockRegion

public void unlockRegion(SoftLock lock)

从接口复制的说明: CachedDomainDataAccess

Called after we have finished the attempted invalidation of the entire region

指定者:

unlockRegion 在接口中 CachedDomainDataAccess

覆盖:

unlockRegion 在类中 AbstractCachedDomainDataAccess

参数:

lock - The lock previously obtained from CachedDomainDataAccess.lockRegion()

lockItem

public SoftLock lockItem(SharedSessionContractImplementor session,
                         Object key,
                         Object version)

从接口复制的说明: CachedDomainDataAccess

We are going to attempt to update/delete the keyed object. This method is used by "asynchronous" concurrency strategies.

The returned object must be passed back to CachedDomainDataAccess.unlockItem(org.hibernate.engine.spi.SharedSessionContractImplementor, java.lang.Object, org.hibernate.cache.spi.access.SoftLock), to release the lock. Concurrency strategies which do not support client-visible locks may silently return null.

指定者:

lockItem 在接口中 CachedDomainDataAccess

参数:

session - Current session.

key - The key of the item to lock

version - The item's current version value

返回:

A representation of our lock on the item; or null.

unlockItem

public void unlockItem(SharedSessionContractImplementor session,
                       Object key,
                       SoftLock lock)

从接口复制的说明: CachedDomainDataAccess

Called when we have finished the attempted update/delete (which may or may not have been successful), after transaction completion. This method is used by "asynchronous" concurrency strategies.

指定者:

unlockItem 在接口中 CachedDomainDataAccess

参数:

session - Current session.

key - The item key

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