Class SyncSet

java.lang.Object

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

EDU.oswego.cs.dl.util.concurrent.SyncSet

All Implemented Interfaces:

Iterable, Collection, Set

Direct Known Subclasses:

SyncSortedSet

public class SyncSet
extends SyncCollection
implements Set

SyncSets wrap Sync-based control around java.util.Sets. They support two additional reader operations than do SyncCollection: hashCode and equals.
