org.apache.commons.jcs.auxiliary.disk.indexed.IndexedDiskCache.LRUMapCountLimited

All Implemented Interfaces:

Map<K,IndexedDiskElementDescriptor>

Enclosing class:

IndexedDiskCache<K,V>

public class IndexedDiskCache.LRUMapCountLimited
extends LRUMap<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 elements to decide, when to throw away an element

Method Detail

processRemovedLRU

protected void processRemovedLRU(K key,
                                 IndexedDiskElementDescriptor value)

This is called when the may key size is reached. The least recently used item will be passed here. We will store the position and size of the spot on disk in the recycle bin.
