Class BaseCacheFactory<Key,Value,Config>

java.lang.Object

cascading.util.cache.BaseCacheFactory<Key,Value,Config>

All Implemented Interfaces:

CascadingFactory<Config,CascadingCache<Key,Value>>

Direct Known Subclasses:

DirectMappedCacheFactory, LRUHashMapCacheFactory, OrderedHashMapCacheFactory

public abstract class BaseCacheFactory<Key,Value,Config>
extends java.lang.Object
implements CascadingFactory<Config,CascadingCache<Key,Value>>

Base class for all CacheFactories for creating CascadingCache instances. Each sub-assembly using the CascadingCache facilities has it's own sub-class of this factory so that different Caches can be used for different parts of the same flow.

A CacheEvictionCallback can be set and it will be given to each Cache instance created by the factory. If none is set, the Factory will use CacheEvictionCallback.NULL, which is a no-op implementation of the CacheEvictionCallback interface.
