Class ConcurrentHashSet
java.lang.Object
com.jivesoftware.util.ConcurrentHashSet
- All Implemented Interfaces:
- java.lang.Iterable, java.util.Collection, java.util.Set
public class ConcurrentHashSet
- extends java.lang.Object
- implements java.util.Set
Wraps the standard HashSet with concurrent ReadWriteLock protections and iterator over copy of contents.
It is a common pattern in database backed classes to provide in-memory caches of database sets
using thread safe behaviors. This class provides a simple method of providing such a set.
