LongEnumeration (OpenJ9 JDK 11)

All Superinterfaces:

Enumeration
```
public interface LongEnumeration
extends Enumeration
```
This interface provides an enumeration of long values. As well as the methods provided by its superclass it also offers a nextLong() method to get the value as a primitive thus avoiding the overhead of an object creation. In addition it provides an optional numberOfElements() method which returns the total number of elements in the enumeration. If this optional method is supported then the provider will return true for the hasNumberOfElements() method.
