| CacheLoader | | public interface CacheLoader (Code) | | A CacheLoader is used by a cache to request missing data on a cache miss,
or to pre-load specific data into the cache. The CacheLoader is considered
to be part of the application, and not part of the cache implementation
itself, and as such is considered a form of call-back interface.

Return the values associated with each the specified keys in the

CacheLoaderException - the CacheLoader wrap an exception thatoccurs when loading data, such as an exception from the datasource, as a CacheLoaderException to report the failure backto the calling cache |
| loadAll | | public Map<K, V> loadAll(Collection<? extends K> colKeys) throws CacheLoaderException(Code) | | Return the values associated with each the specified keys in the
