Java Source Code / Java Documentation » Portal » uPortal_rel 2 6 1 GA » org.jasig.portal.concurrency.caching   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.jasig.portal.concurrency.caching.ReferenceEntityCache All known Subclasses:   org.jasig.portal.concurrency.caching.ReferenceInvalidatingEntityCache, ReferenceEntityCache public class ReferenceEntityCache implements IEntityCache(Code) Reference implementation of IEntityCache. Each cache holds entities of a single type in an LRUCache, a kind of HashMap. Synchronization for get(), add() and remove() is handled by the LRUCache. At intervals, the cleanupThread kicks off a sweep of the cache to trim it down to its maximum size. author:    Dan Ellentuck version:    $Revision: 36731 $ See Also:   org.jasig.portal.concurrency.caching.LRUCache Inner Class :protected class CacheSweeper implements Runnable Field Summary protected  Map cache      protected  Thread cleanupThread      protected  Class entityType      protected  String simpleTypeName      protected  int sweepIntervalMillis      protected static  int threadID      Constructor Summary public   ReferenceEntityCache(Class type, int maxSize, int maxUnusedTime, int sweepInterval)      ReferenceEntityCache constructor comment.
