Class PspDatedCacheElement<V>

java.lang.Object
edu.internet2.middleware.grouper.pspng.PspDatedCacheElement<V>
Type Parameters:
V -
public class PspDatedCacheElement<V> extends Object
This is a wrapper that stores a value along with the date it was cached. Theoretically, this is not needed if GrouperCache provided access to its Element cached items, but it seems easiest to create a thin wrapper so that GrouperCache's API is not made more complicated. This is used by the PspDatedCache so that cached values can be used only when they're "new enough" to satisfy the current request.
