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:
