java.lang.Object org.hibernate.cache.jbc2.collection.TransactionalAccess
public class TransactionalAccess
This defines the strategy for transactional access to collection data in a pessimistic-locking JBossCache using its 2.x APIs
Constructor Summary | |
---|---|
|
TransactionalAccess(CollectionRegionImpl region)
Create a new TransactionalAccess. |
protected |
TransactionalAccess(CollectionRegionImpl region,
TransactionalAccessDelegate delegate)
Allow subclasses to define the delegate. |
Method Summary | |
---|---|
void |
evict(Object key)
Forcibly evict an item from the cache immediately without regard for transaction isolation. |
void |
evictAll()
Forcibly evict all items from the cache immediately without regard for transaction isolation. |
Object |
get(Object key,
long txTimestamp)
Attempt to retrieve an object from the cache. |
CollectionRegion |
getRegion()
Get the wrapped collection cache region |
SoftLock |
lockItem(Object key,
Object version)
We are going to attempt to update/delete the keyed object. |
SoftLock |
lockRegion()
Lock the entire region |
boolean |
putFromLoad(Object key,
Object value,
long txTimestamp,
Object version)
Attempt to cache an object, after loading from the database. |
boolean |
putFromLoad(Object key,
Object value,
long txTimestamp,
Object version,
boolean minimalPutOverride)
Attempt to cache an object, after loading from the database, explicitly specifying the minimalPut behavior. |
void |
remove(Object key)
Called after an item has become stale (before the transaction completes). |
void |
removeAll()
Called to evict data from the entire region |
void |
unlockItem(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 |
