NSSet (Project Wonder Reference Documentation)

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

Type Parameters:

E - - type of set contents

All Implemented Interfaces:

com.webobjects.foundation._NSFoundationCollection, com.webobjects.foundation.NSCoding, Serializable, Cloneable, Iterable<E>, Collection<E>, Set<E>

Direct Known Subclasses:

NSMutableSet
```
public class NSSet<E>
extends Object
implements Cloneable, Serializable, com.webobjects.foundation.NSCoding, com.webobjects.foundation._NSFoundationCollection, Set<E>
```
NSSet reimplementation to support JDK 1.5 templates. Use with

JDK 1.5 テンプレートをサポートする為の再実装。使用は
```
 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));
