Class SyncSortedMap
java.lang.Object
EDU.oswego.cs.dl.util.concurrent.SyncMap
EDU.oswego.cs.dl.util.concurrent.SyncSortedMap
- All Implemented Interfaces:
- Map, SortedMap
- public class SyncSortedMap
- extends SyncMap
- implements 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.

SyncSortedMap
public SyncSortedMap(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.

SyncSortedMap
public SyncSortedMap(SortedMap map,
Sync readLock,
Sync writeLock)
