Constructor and Description |
---|
ReadOnlyEhcacheEntityRegionAccessStrategy(EhcacheEntityRegion region,
Settings settings)
Create a read-only access strategy accessing the given entity region.
|
Modifier and Type | Method and Description |
---|---|
boolean |
afterInsert(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(java.lang.Object key,
java.lang.Object value,
java.lang.Object currentVersion,
java.lang.Object previousVersion,
SoftLock lock)
Throws UnsupportedOperationException since this cache is read-only
|
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 |
get(java.lang.Object key,
long txTimestamp)
Attempt to retrieve an object from the cache.
|
EntityRegion |
getRegion()
Get the wrapped entity cache region
|
boolean |
insert(java.lang.Object key,
java.lang.Object value,
java.lang.Object version)
This cache is asynchronous hence a no-op
|
SoftLock |
lockItem(java.lang.Object key,
java.lang.Object version)
We are going to attempt to update/delete the keyed object.
|
SoftLock |
lockRegion()
Region locks are not supported.
|
boolean |
putFromLoad(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(java.lang.Object key,
java.lang.Object value,
long txTimestamp,
java.lang.Object version,
boolean minimalPutOverride)
This method is a placeholder for method signatures supplied by interfaces pulled in further down the class
hierarchy.
|
void |
remove(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
|
void |
unlockItem(java.lang.Object key,
SoftLock lock)
A no-op since this cache is read-only
|
void |
unlockRegion(SoftLock lock)
Region locks are not supported - perform a cache clear as a precaution.
|
boolean |
update(java.lang.Object key,
java.lang.Object value,
java.lang.Object currentVersion,
java.lang.Object previousVersion)
Throws UnsupportedOperationException since this cache is read-only
