Interface CacheManager

All Known Implementing Classes:

AmnesiaCacheManager, InMemoryCacheManager

public interface CacheManager

Interface to use caches. Two different kinds of caches have to be supported. One implementing UnawareCache and one implementing Cache. The reason is that we do not need to support some Methods for a properties cache, so that here the a UnawreCache implementation is sufficient. But for configurations we also need the additional method supported by Cache. Its totally legal to use the same Cache implementation for both use-cases.

Method Summary

void	clear(String cacheName) Clears the cache with the given name.
void	clearAll() Removes all keys from all caches.
void	discard(String cacheName) Clears and stops the cache.
Set<String>	getCacheNames() Returns the set of cache names.
Cache<?,?>	getConfigurationsCache(String cacheName) Returns the configurations cache with the given name.
UnawareCache<?,?>	getPropertiesCache(String cacheName) Returns the properties cache with the given name.
void	stop(String cacheName) Stops the cache with the given name.
void	stopAll() Stops all caches, rendering the manager in a stopped state.
