Package EDU.oswego.cs.dl.util.concurrent

Class SyncSortedMap

  • All Implemented Interfaces:
    java.util.Map, java.util.SortedMap
    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.

      Constructors 
      Constructor Description
      SyncSortedMap​(java.util.SortedMap map, ReadWriteLock rwl)
      Create a new SyncSortedMap protecting the given map, and using the given ReadWriteLock to control reader and writer methods.
      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.
      SyncSortedMap​(java.util.SortedMap map, Sync readLock, Sync writeLock)
      Create a new SyncSortedMap protecting the given map, and using the given pair of locks to control reader and writer methods.

        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.
