Class Hashtable.ValueEnumerator

java.lang.Object
  java.util.Hashtable.EntryEnumerator
      java.util.Hashtable.ValueEnumerator

All Implemented Interfaces:: Enumeration

Enclosing class:: Hashtable

private final class Hashtable.ValueEnumerator
extends Hashtable.EntryEnumerator

Enumeration view of this Hashtable, providing sequential access to its values. NOTE: Enumeration is not safe if new elements are put in the table as this could cause a rehash and we'd completely lose our place. Even without a rehash, it is undetermined if a new element added would appear in the enumeration. The spec says nothing about this, but the "Java Class Libraries" book implies that modifications to the hashtable during enumeration causes indeterminate results. Don't do it!

Field Summary

(package private) int idx
          Current index in the physical hash table.

(package private) Hashtable.HashEntry next
          Entry which will be returned by the next nextElement() call.
