Constructor Details

MapCacheStore

public MapCacheStore(Map<K,V> map)

Create a CacheStore that delegates to a Map.

Parameters:

map - the Map to use as the underlying store for this CacheStore

Method Details

load

public V load(K key)

Return the value associated with the specified key, or null if the key does not have an associated value in the underlying store.

Specified by:

load in interface CacheLoader<K,V>

Specified by:

load in class AbstractCacheLoader<K,V>

Parameters:

key - key whose associated value is to be returned

Returns:

the value associated with the specified key, or null if no value is available for that key

store

public void store(K key,
 V value)

Store the specified value under the specified key in the underlying store. This method is intended to support both key/value creation and value update for a specific key.

Specified by:

store in interface CacheStore<K,V>

Overrides:

store in class AbstractCacheStore<K,V>

Parameters:

key - key to store the value under

value - value to be stored

storeAll

public void storeAll(Map<? extends K,? extends V> mapEntries)

Store the specified values under the specified keys in the underlying store. This method is intended to support both key/value creation and value update for the specified keys.

Specified by:

storeAll in interface CacheStore<K,V>

Parameters:

mapEntries - a Map of any number of keys and values to store

erase

public void erase(K key)

Remove the specified key from the underlying store if present.

Specified by:

erase in interface CacheStore<K,V>

Overrides:

erase in class AbstractCacheStore<K,V>

Parameters:

key - key to remove from the store

eraseAll

public void eraseAll(Collection<? extends K> colKeys)

Remove the specified keys from the underlying store if present.

Specified by:

eraseAll in interface CacheStore<K,V>

Parameters:

colKeys - keys whose mappings are being removed from the cache

keys

public Iterator<K> keys()

Iterate all keys in the underlying store.

Specified by:

keys in interface IterableCacheLoader<K,V>

Returns:

a read-only iterator of the keys in the underlying store

getMap

public Map<K,V> getMap()

Returns the Map that this CacheStore uses for its storage.

Returns:

the Map that this CacheStore uses

setMap

protected void setMap(Map<K,V> map)

Configures the Map that this CacheStore uses for its storage.

Parameters:

map - the Map that this CacheStore will use
