boolean	afterInsert(SharedSessionContractImplementor session, Object key, Object value, Object version)	Called afterQuery an item has been inserted (afterQuery the transaction completes), instead of calling release().

EntityReadOnlyAccess

public EntityReadOnlyAccess(DomainDataRegion region,
                            CacheKeysFactory cacheKeysFactory,
                            DomainDataStorageAccess storageAccess,

getAccessType

public AccessType getAccessType()

从接口复制的说明: CachedDomainDataAccess

The type of access implemented

insert

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

从接口复制的说明: EntityDataAccess

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

参数:

session - Current session

key - The item key

value - The item

version - The item's version value

返回:

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

afterInsert

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

从接口复制的说明: EntityDataAccess

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

参数:

session - Current session

key - The item key

value - The item

version - The item's version value

返回:

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

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

覆盖:

unlockItem 在类中 AbstractEntityDataAccess

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)

update

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

从接口复制的说明: EntityDataAccess

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

参数:

session - Current session

key - The item key

value - The item

currentVersion - The item's current version value

previousVersion - The item's previous version value

返回:

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

afterUpdate

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

从接口复制的说明: EntityDataAccess

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

参数:

session - Current session

key - The item key

value - The item

currentVersion - The item's current version value

previousVersion - The item's previous version value

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