Class RecentHistoryList

java.lang.Object
  com.jivesoftware.forum.util.RecentHistoryList

All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable, java.util.Collection, java.util.List

public class RecentHistoryList
extends java.lang.Object
implements java.util.List, java.io.Serializable

A list that manages storing item history. The oldest item in the list will be removed when the list has reached the specified maximum size. The list is not allowed to contain duplicates, thus if a duplicate item exists, the old item will be removed and the new item will be added. Items will be added to the front of the list so iterating over this list will produce most recent items first. This list is syncronized, so it can safely be stored and accessed in the session. The internal implementation of the list is a @{link LinkedList} since it is best optimized for this implementation.
