org.apache.jcs.auxiliary.disk.indexed
Class IndexedDiskCache.LRUMap

java.lang.Object
  org.apache.jcs.utils.struct.LRUMap<K,V>
      org.apache.jcs.auxiliary.disk.LRUMapJCS<K,IndexedDiskElementDescriptor>
          org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCache.LRUMap

All Implemented Interfaces:: Map<K,IndexedDiskElementDescriptor>

Enclosing class:: IndexedDiskCache<K extends Serializable,V extends Serializable>

public class IndexedDiskCache.LRUMap
extends LRUMapJCS<K,IndexedDiskElementDescriptor>
extends LRUMapJCS<K,IndexedDiskElementDescriptor>

Class for recycling and lru. This implements the LRU overflow callback, so we can add items to the recycle bin.
