java.lang.Object
  com.webobjects.foundation.NSSet<E>

Type Parameters:

E - type of set contents

All Implemented Interfaces:

public class NSSet<E>
extends Object
implements Cloneable, Serializable, NSCoding, _NSFoundationCollection, Set<E>

NSSet reimplementation to support JDK 1.5 templates. Use with

 NSSet<E> setA = new NSSet<E>(NSArray<E> listA);
 NSSet<E> setB = new NSSet<E>(NSArray<E> listB);
 logger.debug("intersection contains " + setA.setByIntersectingSet(setB));
