LRUCache

public LRUCache(int capacity)

Creates an LRU cache with the specified capacity. If this capacity is exceeded the lest-recently accessed entry will be removed.

Parameters:

capacity - Maximum number of entries the LRUCache can store.

Method Details

removeEldestEntry

protected boolean removeEldestEntry(Map.Entry<K,V> eldest)

Overrides:

removeEldestEntry in class LinkedHashMap<K,V>
