public class SyncSortedMap extends SyncMap implements java.util.SortedMap
SyncSortedMaps wrap Sync-based control around java.util.SortedMaps. They support the following additional reader operations over SyncMap: comparator, subMap, headMap, tailMap, firstKey, lastKey.- See Also:

SyncSortedMap
public SyncSortedMap(java.util.SortedMap map, Sync sync)
Create a new SyncSortedMap protecting the given map, and using the given sync to control both reader and writer methods. Common, reasonable choices for the sync argument include Mutex, ReentrantLock, and Semaphores initialized to 1.
