    • eligibleForRemovalFromCache

      public boolean eligibleForRemovalFromCache(StatefulEJBContext ctx, Serializable sessionKey)
      Called by StatefulSessionContainer before passivation to determine whether or not removal-timeout has elapsed for a cache item. If so, it will be directly removed instead of passivated. See issue 16188.

      public Iterator values()
      get an Iterator for the values stored in the cache
      Specified by:

    • shutdown

      public void shutdown()

    • trimTimedoutItems

      public void trimTimedoutItems(int maxTrimCount)
      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

    • trimUnSortedTimedoutItems

      public void trimUnSortedTimedoutItems(int maxCount)
      This method picks idle items from a cache which does not have a sorted LRU list NRU cache at light loads and FIFO caches do not maintain a LRU list and hence they have to scan the entire cache and select victims
