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.
