Deprecated.
Replaced by java.util.Collections#enumeration(..)
```
@Deprecated
public final class Enumerator<T>
extends Object
implements Enumeration<T>
```
Adapter class that wraps an Enumeration around a Java2 collection classes object Iterator so that existing APIs returning Enumerations can easily run on top of the new collections. Constructors are provided to easily create such wrappers.
