Class LazyRemovalList<T>

java.lang.Object
org.jgroups.util.LazyRemovalList<T>
Type Parameters:
T - T
public class LazyRemovalList<T> extends Object
List which doesn't remove elements on remove(), removeAll() or retainAll(), but only removes elements when a configurable size limit has been exceeded. In that case, all elements marked as removable and older than a configurable time are evicted. Elements are marked as removable by remove(), removeAll() and retainAll(). When an elements is marked as removable, but later reinserted, the mark is removed.
Note that methods get() and remove() iterate through the list (linear cost), so large lists will be slow.
