Interface Enumeration<E>

All Known Implementing Classes:

AllPermissionCollection.SingletonEnumeration, ConcurrentHashMap.KeyIterator, ConcurrentHashMap.ValueIterator, EmptyEnumeration, Permissions.MetaEnumeration, StringTokenizer, TwoEnumerationsInOne

public interface Enumeration<E>

A legacy iteration interface.

New code should use Iterator instead. Iterator replaces the enumeration interface and adds a way to remove elements from a collection.

If you have an Enumeration and want a Collection, you can use Collections.list(java.util.Enumeration) to get a List.

If you need an Enumeration for a legacy API and have a Collection, you can use Collections.enumeration(java.util.Collection).
