Class SyncList

java.lang.Object

EDU.oswego.cs.dl.util.concurrent.SyncCollection

EDU.oswego.cs.dl.util.concurrent.SyncList

All Implemented Interfaces:

java.lang.Iterable, java.util.Collection, java.util.List

public class SyncList
extends SyncCollection
implements java.util.List

SyncLists wrap Sync-based control around java.util.Lists. They support the following additional reader operations over SyncCollection: hashCode, equals, get, indexOf, lastIndexOf, subList. They support additional writer operations remove(int), set(int), add(int), addAll(int). The corresponding listIterators and are similarly extended.

Constructor Detail

SyncList

public SyncList(java.util.List list,
                Sync sync)

Create a new SyncList 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.

SyncList

public SyncList(java.util.List list,
                ReadWriteLock rwl)

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

SyncList

public SyncList(java.util.List list,
                Sync readLock,
                Sync writeLock)

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