Class CountLimited

  • All Implemented Interfaces:
    java.util.Map<java.lang.Object,​java.lang.Object>, Cache
    public final class CountLimited
extends AbstractBaseCache
    CountLimited is a count limted least-recently-used Map. Every object being put in the Map will live until the map is full. If the map is full, the least recently used object will be disposed.

    The capacity is passed to the cache at initialization by the individual cache property capacity which defines the maximum number of objects the cache can hold. If not specified a default capacity of 30 objects will be used.
