Class IntHashSet
java.lang.Object
net.sf.saxon.sort.IntHashSet
- All Implemented Interfaces:
Serializable
,IntSet
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.
