Method Detail

itemAccessed

protected void itemAccessed(com.sun.appserv.util.cache.BaseCache.CacheItem item)

Overrides:

itemAccessed in class LruSessionCache

itemRefreshed

protected void itemRefreshed(com.sun.appserv.util.cache.BaseCache.CacheItem item,
                             int oldSize)

Overrides:

itemRefreshed in class com.sun.appserv.util.cache.LruCache

trimTimedoutItems

public void trimTimedoutItems(int maxCount)

Description copied from class: LruSessionCache

trim the timedOut entries from the cache. This call is to be scheduled by a thread managed by the container. In this case a sorted LRU list exists based on access time and this list is scanned

Overrides:

trimTimedoutItems in class LruSessionCache
