All Implemented Interfaces:

java.util.Enumeration<Tuple>, javax.naming.NamingEnumeration<Tuple>

public class TupleEnumeration
extends java.lang.Object
implements javax.naming.NamingEnumeration<Tuple>

A NamingEnumeration that returns underlying Iterator values for a single key as Tuples.

WARNING: The tuple returned is reused every time for efficiency and populated a over and over again with the new value. The key never changes.
