Examples of ConcurrentNavigableMap

java.util.concurrent.ConcurrentNavigableMap
A {@link ConcurrentMap} supporting {@link NavigableMap} operations,and recursively so for its navigable sub-maps.
This interface is a member of the Java Collections Framework. @author Doug Lea @param < K> the type of keys maintained by this map @param < V> the type of mapped values @since 1.6
