Method Summary

Modifier and Type	Method	Description
boolean	afterInsert(SharedSessionContractImplementor session, Object key, Object value, Object version)	Called after an item has been inserted (after the transaction completes), instead of calling #release.
boolean	afterUpdate(SharedSessionContractImplementor session, Object key, Object value, Object currentVersion, Object previousVersion, SoftLock lock)	Called after an item has been updated (after the transaction completes), instead of calling #release.
AccessType	getAccessType()	The type of access implemented
boolean	insert(SharedSessionContractImplementor session, Object key, Object value, Object version)	Called after an item has been inserted (before the transaction completes), instead of calling CachedDomainDataAccess.evict(java.lang.Object).
void	unlockItem(SharedSessionContractImplementor session, Object key, SoftLock lock)	Notify that an attempt to update or delete the keyed object has completed, with or without success, after transaction completion.
boolean	update(SharedSessionContractImplementor session, Object key, Object value, Object currentVersion, Object previousVersion)	Called after an item has been updated (before the transaction completes), instead of calling CachedDomainDataAccess.evict(java.lang.Object).

Method Details

getAccessType

public AccessType getAccessType()

Description copied from interface: CachedDomainDataAccess

The type of access implemented

insert

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

Description copied from interface: EntityDataAccess

Called after an item has been inserted (before the transaction completes), instead of calling CachedDomainDataAccess.evict(java.lang.Object). This method is used by "synchronous" concurrency strategies.

Parameters:

session - Current session

key - The item key

value - The item

version - The item's version value

Returns:

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

afterInsert

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

Description copied from interface: EntityDataAccess

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

Parameters:

session - Current session

key - The item key

value - The item

version - The item's version value

Returns:

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

unlockItem

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

Description copied from interface: CachedDomainDataAccess

Notify that an attempt to update or delete the keyed object has completed, with or without success, after transaction completion. This operation is used by "asynchronous" concurrency strategies.

Specified by:

unlockItem in interface CachedDomainDataAccess

Overrides:

unlockItem in class AbstractEntityDataAccess

Parameters:

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)

Description copied from interface: EntityDataAccess

Called after an item has been updated (before the transaction completes), instead of calling CachedDomainDataAccess.evict(java.lang.Object). This method is used by "synchronous" concurrency strategies.

Parameters:

session - Current session

key - The item key

value - The item

currentVersion - The item's current version value

previousVersion - The item's previous version value

Returns:

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)

Description copied from interface: EntityDataAccess

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

Parameters:

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)

Returns:

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