Modifier and Type | Method and Description |
---|---|
boolean |
afterInsert(SessionImplementor session,
java.lang.Object key,
java.lang.Object value,
java.lang.Object version)
Called after an item has been inserted (after the transaction completes),
instead of calling release().
|
boolean |
afterUpdate(SessionImplementor session,
java.lang.Object key,
java.lang.Object value,
java.lang.Object currentVersion,
java.lang.Object previousVersion,
SoftLock lock)
Called after an item has been updated (after the transaction completes),
instead of calling release().
|
void |
evict(java.lang.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.
|
java.lang.Object |
generateCacheKey(java.lang.Object id,
EntityPersister persister,
SessionFactoryImplementor factory,
java.lang.String tenantIdentifier)
To create instances of keys for this region, Hibernate will invoke this method
exclusively so that generated implementations can generate optimised keys.
|
java.lang.Object |
get(SessionImplementor session,
java.lang.Object key,
long txTimestamp)
Attempt to retrieve an object from the cache.
|
java.lang.Object |
getCacheKeyId(java.lang.Object cacheKey)
Performs reverse operation to
EntityRegionAccessStrategy.generateCacheKey(Object, EntityPersister, SessionFactoryImplementor, String) |
EntityRegion |
getRegion()
Get the wrapped entity cache region
|
boolean |
insert(SessionImplementor session,
java.lang.Object key,
java.lang.Object value,
java.lang.Object version)
Called after an item has been inserted (before the transaction completes),
instead of calling evict().
|
SoftLock |
lockItem(SessionImplementor session,
java.lang.Object key,
java.lang.Object version)
We are going to attempt to update/delete the keyed object.
|
SoftLock |
lockRegion()
Lock the entire region
|
boolean |
putFromLoad(SessionImplementor session,
java.lang.Object key,
java.lang.Object value,
long txTimestamp,
java.lang.Object version)
Attempt to cache an object, after loading from the database.
|
boolean |
putFromLoad(SessionImplementor session,
java.lang.Object key,
java.lang.Object value,
long txTimestamp,
java.lang.Object version,
boolean minimalPutOverride)
Attempt to cache an object, after loading from the database, explicitly
specifying the minimalPut behavior.
|
void |
remove(SessionImplementor session,
java.lang.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(SessionImplementor session,
java.lang.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
|
boolean |
update(SessionImplementor session,
java.lang.Object key,
java.lang.Object value,
java.lang.Object currentVersion,
java.lang.Object previousVersion)
Called after an item has been updated (before the transaction completes),
instead of calling evict().
