Modifier and Type	Method	Description
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().
boolean	afterUpdate(SharedSessionContractImplementor session, Object key, Object value, Object currentVersion, Object previousVersion, SoftLock lock)	Called afterQuery an item has been updated (afterQuery 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 afterQuery an item has been inserted (beforeQuery the transaction completes), instead of calling evict().
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.
boolean	update(SharedSessionContractImplementor session, Object key, Object value, Object currentVersion, Object previousVersion)	Called afterQuery an item has been updated (beforeQuery the transaction completes), instead of calling evict().

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 afterQuery an item has been inserted (beforeQuery the transaction completes), instead of calling evict(). 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 afterQuery an item has been inserted (afterQuery 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

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.

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 afterQuery an item has been updated (beforeQuery the transaction completes), instead of calling evict(). 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 afterQuery an item has been updated (afterQuery 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?
