Class FixedSizeHashMap<K,​V>

  • Type Parameters:
    K - the key type
    V - the value type
    All Implemented Interfaces:, java.lang.Cloneable, java.util.Map<K,​V>
    Direct Known Subclasses:

    public class FixedSizeHashMap<K,​V>
    extends java.util.LinkedHashMap<K,​V>
    A simple implementation of a LRU map that will throw away entries that exceed the given maximum size.

    If you would like a LRU based upon access-order, then use the LRUMap.
