Class WcmMRUCollection

java.lang.Object
  extended bycom.filenet.wcm.toolkit.util.WcmMRUCollection
All Implemented Interfaces:
java.util.Collection

public class WcmMRUCollection
extends java.lang.Object
implements java.util.Collection

This class provides a limited amount of "most recently used" storage, with a pre-defined limit on how many items can be stored. When you add a new item, if you're at the limit, then the least recently used item gets thrown away to make space for the new one, which is added to the top of the list.

This class implements Collection interface, which means the only way to access the elements is using iterator() method. This is simular to Sets, but there are no constrains on the objects that can be stored. When iterating through the elements, elements returned by Iterator.next() method are not moved to the top of the list.
