Class ApplicationCacheAccessor

java.lang.Object
org.silverpeas.kernel.cache.service.ApplicationCacheAccessor
All Implemented Interfaces:
CacheAccessor<ExternalCache>
public class ApplicationCacheAccessor extends Object implements CacheAccessor<ExternalCache>
An accessor to a cache whose lifetime is within the whole application runtime. This accessor uses a specific implementation of the cache that is retrieved by using the Java Service Loader mechanism. So, through this accessor you can use tiers caching subsystem like Infinispan or EhCache for example, for better performance. This is why this accessor maintains only a single instance of such a cache. In the case no external cache is available, then by default an in-memory cache is used, meaning no additional cache functionalities (like time-to-live for example) are supported.
