EDU.oswego.cs.dl.util.concurrent
Class SyncSortedSet

java.lang.Object
  EDU.oswego.cs.dl.util.concurrent.SyncCollection
      EDU.oswego.cs.dl.util.concurrent.SyncSet
          EDU.oswego.cs.dl.util.concurrent.SyncSortedSet

All Implemented Interfaces:

java.lang.Iterable, java.util.Collection, java.util.Set, java.util.SortedSet

public class SyncSortedSet
extends SyncSet
implements java.util.SortedSet

SyncSortedSets wrap Sync-based control around java.util.SortedSets. They support the following additional reader operations over SyncCollection: comparator, subSet, headSet, tailSet, first, last.

SyncSortedSet

public SyncSortedSet(java.util.SortedSet set,
                     Sync sync)

Create a new SyncSortedSet protecting the given collection, 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.
