| Modifier and Type | Method and Description |
|---|---|
boolean |
afterInsert(Object key,
Object value,
Object version)
Called after an item has been inserted (after the transaction completes),
instead of calling release().
|
boolean |
afterUpdate(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().
|
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.
|
EntityRegion |
getRegion()
Get the wrapped entity cache region
|
boolean |
insert(Object key,
Object value,
Object version)
Called after an item has been inserted (before the transaction completes),
instead of calling evict().
|
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
|
boolean |
update(Object key,
Object value,
Object currentVersion,
Object previousVersion)
Called after an item has been updated (before the transaction completes),
instead of calling evict().
