Constructor
|
| Modifier and Type | Method and Description |
|---|---|
void |
addStoreListener(StoreListener listener)

|
boolean |
bufferFull()
Some store types, such as the disk stores can fill their write buffers if puts
come in too fast.
|
boolean |
containsKey(Object key)
A check to see if a key is in the Store.
|
boolean |
containsKeyInMemory(Object key)
A check to see if a key is in the Store and is currently held in memory.
|
boolean |
containsKeyOffHeap(Object key)
A check to see if a key is in the Store and is currently held off-heap.

|
void |

|
Element |
get(Object key)
Gets an item from the cache.
|
Map<Object,Element> |
getAll(Collection<?> keys)
Retries the elements associated with a set of keys and update the statistics
Keys which are not present in the cache will have null values associated
with them in the returned map

Map<Object,Element> |

Keys which are not present in the cache will have null values associated
with them in the returned map

|
Element |
removeElement(Element element,
ElementValueComparator comparator)
Remove the Element mapped to the key for the supplied element if the value of the supplied Element
is equal to the value of the cached Element.
|
void |
removeStoreListener(StoreListener listener)

|
Element |
removeWithWriter(Object key,
CacheWriterManager writerManager)
Removes an item from the store and the cache writer manager in an atomic operation.
|
Element |
