Constructor Detail

FIFOSessionCache

public FIFOSessionCache(String cacheName,
                        SFSBContainerCallback container,
                        int cacheIdleTime,
                        int removalTime)

Method Detail

itemAccessed

protected void itemAccessed(BaseCache.CacheItem item)

Description copied from class: LruCache

this item is accessed

Overrides:

itemAccessed in class LruSessionCache

Parameters:

item - CacheItem accessed Cache bucket is already synchronized by the caller

itemRefreshed

protected void itemRefreshed(BaseCache.CacheItem item,
                             int oldSize)

Description copied from class: LruCache

item value has been refreshed

Overrides:

itemRefreshed in class LruCache

Parameters:

item - CacheItem that was refreshed

oldSize - size of the previous value that was refreshed Cache bucket is already synchronized by the caller

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
