public class BoundedList<T>
extends java.util.concurrent.ConcurrentLinkedQueue<T>

A bounded subclass of LinkedList, oldest elements are removed once max capacity is exceeded. Note that this class is not synchronized (like LinkedList). Don't use this for high performance, as size() has a linear cost. But in most scenarios, this class is used for maintaining a history, e.g. of digests or views, so perf is not critical.
