All Implemented Interfaces:

java.lang.Cloneable, Ehcache

public class RefreshingSelfPopulatingCache
extends SelfPopulatingCache

Extension of SelfPopulatingCache that schedules a periodic call of SelfPopulatingCache.refresh() via the specified TaskSchedulerAdapter. Also overrides refreshElement(Element, Ehcache, boolean) to allow for asynchronous refresh of elements iff an Executor was provided to the constructor.
