IntArraySet (saxon8 JavaDoc)

java.lang.Object
- net.sf.saxon.sort.IntArraySet

All Implemented Interfaces:

java.io.Serializable
```
public class IntArraySet
extends java.lang.Object
implements 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. It does implement the same interface as IntHashSet, although this is currently not defined as an explicit interface.
This implementation of a set of integers is optimized to use very little storage and to provide fast comparison of two sets. The equals() method determines whether two sets contain the same integers.
Not thread safe.
