Constructor
|

Status |
getStatus()
Returns the cache status.
|
CacheConfiguration.TransactionalMode |
getTransactionalMode()
Get the transactional mode of this store.
|
boolean |
hasAbortedSizeOf()
Checks if the cache may contain elements for which the SizeOf engine gave up and only
partially calculated the size.
|
boolean |
isCacheCoherent()
Indicates whether this store provides a coherent view of all the elements
in a cache.
|
boolean |
isClusterCoherent()
Returns true if the cache is in coherent mode cluster-wide.
|
boolean |
isNodeCoherent()
Returns true if the cache is in coherent mode for the current node.
|
boolean |
isPinned(Object key)
Check if the key is pinned
|
void |
setAttributeExtractors(Map<String,AttributeExtractor> extractors)
Inform this store of the configured attribute extractors.
|
void |
setInMemoryEvictionPolicy(Policy policy)
Sets the eviction policy strategy.
|
void |
setNodeCoherent(boolean coherent)
Sets the cache in coherent or incoherent mode for the current node depending on the parameter.
|
void |
setPinned(Object key,
boolean pinned)
Mark the key as pinned or not
|
Element |
unlockedGet(Object key)
Gets the value associated with the key without acquiring any locks.
|
Element |
unlockedGetQuiet(Object key)
Same as
TerracottaStore.unlockedGet(Object) but does not update statistics |
void |
unpinAll()
unpin all pinned keys
|
Element |
unsafeGet(Object key)
Returns the local value associated with the key.
|
Element |
unsafeGetQuiet(Object key)
Same as
TerracottaStore.unsafeGet(Object) but does not update last usage statistics |
void |
waitUntilClusterCoherent()
This method waits until the cache is in coherent mode in all the connected nodes.

public void setNodeCoherent(boolean coherent)
setNodeCoherent(true) when the cache is already in coherent mode or
calling setNodeCoherent(false) when already in incoherent mode will be a no-op.
It applies to coherent clustering mechanisms only e.g. TerracottasetNodeCoherent in interface StoresetNodeCoherent in class AbstractStorecoherent - true transitions to coherent mode, false to incoherent modeStore.setNodeCoherent(boolean)public boolean isNodeCoherent()

Use Store.isNodeCoherent() to find out if the cache is coherent in the current node in the clusterisCacheCoherent in interface StoreisCacheCoherent in class AbstractStoretrue if the store is coherent; or false if the
