Class CopyOnWriteSortedCache<T extends Comparable<T>>

java.lang.Object
com.atlassian.jira.util.collect.CopyOnWriteSortedCache<T>
Type Parameters:
T - the element type.
All Implemented Interfaces:
Iterable<T>
public class CopyOnWriteSortedCache<T extends Comparable<T>> extends Object implements Iterable<T>
Simple copy-on-write ordered cache with Set semantics. This implementation supports add/remove and replace all of elements.

Note that because this implementation uses JVM-local locks, it is unsuitable for use in a clustered environment. It should therefore not be used by core JIRA for data that needs to be consistent across the cluster.
