- net.sf.saxon.sort.IntHashSet

All Implemented Interfaces:

java.io.Serializable, IntSet
```
public class IntHashSet
extends java.lang.Object
implements IntSet, java.io.Serializable
```
Set of int values. This class is modelled on the java.net.Set interface, but it does not implement this interface, because the set members are int's rather than Objects.
Not thread safe.

Author:

Dominique Devienne, Michael Kay: retrofitted to JDK 1.4, added iterator()
