Class SyncSet
java.lang.Object
EDU.oswego.cs.dl.util.concurrent.SyncCollection
EDU.oswego.cs.dl.util.concurrent.SyncSet
- All Implemented Interfaces:
- java.lang.Iterable, java.util.Collection, java.util.Set
- Direct Known Subclasses:
- SyncSortedSet
public class SyncSet
- extends SyncCollection
- implements java.util.Set
SyncSets wrap Sync-based control around java.util.Sets.
They support two additional reader operations than do
SyncCollection: hashCode and equals.
