java.lang.Object
oracle.stellent.wcm.server.content.impl.GlobalContentCache
public class GlobalContentCache
Cache of the content items used in the WCM server. Employs a locking mechanism so this class is safe to share among threads. Has a concept of maximum size using LRU-style alogrithm. Also listens for Content Events to remove items asynchronously and exposes a cache-callback interface to remove items as they are accessed.
