Constructor and Description |
---|
ReadWriteEhcacheEntityRegionAccessStrategy(EhcacheEntityRegion region,
SessionFactoryOptions settings)
Create a read/write access strategy accessing the given entity region.
|
Modifier and Type | Method and Description |
---|---|
boolean |
afterInsert(SharedSessionContractImplementor 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(SharedSessionContractImplementor 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().
|
protected void |
decrementLock(java.lang.Object key,
org.hibernate.cache.ehcache.internal.strategy.AbstractReadWriteEhcacheAccessStrategy.Lock lock)
Unlock and re-put the given key, lock combination.
|
void |
evict(java.lang.Object key)
Remove the given mapping without regard to transactional safety
|
void |
evictAll()
Remove all mappings without regard to transactional safety
|
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(SharedSessionContractImplementor session,
java.lang.Object key,
long txTimestamp)
Returns
null if the item is not readable. |
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
|
protected void |
handleLockExpiry(java.lang.Object key,
org.hibernate.cache.ehcache.internal.strategy.AbstractReadWriteEhcacheAccessStrategy.Lockable lock)
Handle the timeout of a previous lock mapped to this key
|
boolean |
insert(SharedSessionContractImplementor 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(SharedSessionContractImplementor session,
java.lang.Object key,
java.lang.Object version)
Soft-lock a cache item.
|
SoftLock |
lockRegion()
Region locks are not supported.
|
boolean |
putFromLoad(SharedSessionContractImplementor session,
java.lang.Object key,
java.lang.Object value,
long txTimestamp,
java.lang.Object version)
This method is a placeholder for method signatures supplied by interfaces pulled in further down the class
hierarchy.
|
boolean |
putFromLoad(SharedSessionContractImplementor session,
java.lang.Object key,
java.lang.Object value,
long txTimestamp,
java.lang.Object version,
boolean minimalPutOverride)
Returns
false and fails to put the value if there is an existing un-writeable item mapped to this
key. |
protected T |
region()
The wrapped Hibernate cache region.
|
void |
remove(SharedSessionContractImplementor session,
java.lang.Object key)
A no-op since this is an asynchronous cache access strategy.
|
void |
removeAll()
Called to evict data from the entire region
|
protected SessionFactoryOptions |
settings()
The settings for this persistence unit.
|
void |
unlockItem(SharedSessionContractImplementor session,
java.lang.Object key,
SoftLock lock)
Soft-unlock a cache item.
|
void |
unlockRegion(SoftLock lock)
Region locks are not supported - perform a cache clear as a precaution.
|
boolean |
update(SharedSessionContractImplementor 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().
