void | evict(Object key) - Forcibly evict an item from the cache immediately without regard for transaction
isolation.

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 | 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.

destroy
public void destroy()
get
public Object get(Object key,
long txTimestamp)
throws CacheException
Attempt to retrieve an object from the cache. Mainly used in attempting
to resolve entities/collections from the second level cache.
- get in interface CollectionRegionAccessStrategy
key
- The key of the item to be retrieved.txTimestamp
- a timestamp prior to the transaction start time
- the cached object or null
lockItem
public SoftLock lockItem(Object key,
Object version)
throws CacheException
We are going to attempt to update/delete the keyed object. This
method is used by "asynchronous" concurrency strategies.
The returned object must be passed back to release(), to release the
lock. Concurrency strategies which do not support client-visible
locks may silently return null.
- lockItem in interface CollectionRegionAccessStrategy
key
- The key of the item to lockversion
- The item's current version value
- A representation of our lock on the item; or null.
putFromLoad
public boolean putFromLoad(Object key,
Object value,
long txTimestamp,
Object version)
throws CacheException
Attempt to cache an object, after loading from the database.
- putFromLoad in interface CollectionRegionAccessStrategy
key
- The item keyvalue
- The itemtxTimestamp
- a timestamp prior to the transaction start timeversion
- the item version number
- true if the object was successfully cached
putFromLoad
public boolean putFromLoad(Object key,
Object value,
long txTimestamp,
Object version,
boolean minimalPutOverride)
throws CacheException
Attempt to cache an object, after loading from the database, explicitly
specifying the minimalPut behavior.
- putFromLoad in interface CollectionRegionAccessStrategy
key
- The item keyvalue
- The itemtxTimestamp
- a timestamp prior to the transaction start timeversion
- the item version numberminimalPutOverride
- Explicit minimalPut flag
- true if the object was successfully cached
remove
public void remove(Object key)
throws CacheException
Called after an item has become stale (before the transaction completes).
This method is used by "synchronous" concurrency strategies.
- remove in interface CollectionRegionAccessStrategy
key
- The key of the item to remove
unlockItem
public void unlockItem(Object key,
SoftLock lock)
throws CacheException
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.
