Constructor Details

CacheLoaderCacheStore

public CacheLoaderCacheStore(CacheLoader loader)

Construct a CacheLoaderCacheStore.

Parameters:

loader - the CacheLoader to wrap

Method Details

load

public Object load(Object oKey)

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

Specified by:

load in class AbstractCacheLoader

Parameters:

oKey - 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

loadAll

public Map loadAll(Collection colKeys)

Return the values associated with each the specified keys in the passed collection. If a key does not have an associated value in the underlying store, then the return map will not have an entry for that key.

The default implementation of this method calls CacheLoader.load(K) for each key in the supplied Collection. Implementations that can optimize multi-key operations should override this default implementation.

Parameters:

colKeys - a collection of keys to load

Returns:

a Map of keys to associated values for the specified keys

getCacheLoader

protected CacheLoader getCacheLoader()

The wrapped CacheLoader.

Returns:

the underlying CacheLoader that this CacheStore wraps
