## org.jgroups.blocks
Class LazyRemovalCache<K,V>

    java.lang.Object
      org.jgroups.blocks.LazyRemovalCache<K,V>

    public class LazyRemovalCache<K,V>

extends java.lang.Object

Cache 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.
