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:

Iterable, Collection, SequencedCollection, SequencedSet, Set, SortedSet

public class SyncSortedSet
extends SyncSet
implements 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.

Constructor Details

SyncSortedSet

public SyncSortedSet(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.

SyncSortedSet

public SyncSortedSet(SortedSet set,
 ReadWriteLock rwl)

Create a new SyncSortedSet protecting the given set, and using the given ReadWriteLock to control reader and writer methods.

SyncSortedSet

public SyncSortedSet(SortedSet set,
 Sync readLock,
 Sync writeLock)

Create a new SyncSortedSet protecting the given set, and using the given pair of locks to control reader and writer methods.
