Object	generateCacheKey(Object id, CollectionPersister persister, SessionFactoryImplementor factory, String tenantIdentifier)	To create instances of CollectionCacheKey for this region, Hibernate will invoke this method exclusively so that generated implementations can generate optimised keys.
Object	getCacheKeyId(Object cacheKey)	Performs reverse operation to CollectionDataAccess.generateCacheKey(java.lang.Object, org.hibernate.persister.collection.CollectionPersister, org.hibernate.engine.spi.SessionFactoryImplementor, java.lang.String)
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

AbstractCollectionDataAccess

public AbstractCollectionDataAccess(DomainDataRegion region,
                                    CacheKeysFactory keysFactory,
                                    DomainDataStorageAccess storageAccess,
                                    CollectionDataCachingConfig config)

方法详细资料

generateCacheKey

public Object generateCacheKey(Object id,
                               CollectionPersister persister,
                               SessionFactoryImplementor factory,
                               String tenantIdentifier)

从接口复制的说明: CollectionDataAccess

To create instances of CollectionCacheKey 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 CollectionDataAccess

参数:

id - the primary identifier of the Collection

persister - the descriptor of the collection for which a key is being generated

factory - a reference to the current SessionFactory

tenantIdentifier - the tenant id, or null if multi-tenancy is not being used.

返回:

a key which can be used to identify this collection on this same region

getCacheKeyId

public Object getCacheKeyId(Object cacheKey)

从接口复制的说明: CollectionDataAccess

Performs reverse operation to CollectionDataAccess.generateCacheKey(java.lang.Object, org.hibernate.persister.collection.CollectionPersister, org.hibernate.engine.spi.SessionFactoryImplementor, java.lang.String)

指定者:

getCacheKeyId 在接口中 CollectionDataAccess

参数:

cacheKey - key previously returned from CollectionDataAccess.generateCacheKey(java.lang.Object, org.hibernate.persister.collection.CollectionPersister, org.hibernate.engine.spi.SessionFactoryImplementor, java.lang.String)

返回:

original key passed to CollectionDataAccess.generateCacheKey(java.lang.Object, org.hibernate.persister.collection.CollectionPersister, org.hibernate.engine.spi.SessionFactoryImplementor, java.lang.String)

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)

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()
