- Enclosing class:
- IndexedDiskCache<K,V> 
public class IndexedDiskCache.LRUMapSizeLimited
extends AbstractLRUMap<K,IndexedDiskElementDescriptor> 
Class for recycling and lru. This implements the LRU overflow callback, so we can add items
 to the recycle bin. This class counts the size element to decide, when to throw away an element
