Class LinkedHashtable<K,​V>

java.lang.Object
java.util.Dictionary<K,​V>
java.util.Hashtable<K,​V>
org.apache.tools.ant.util.LinkedHashtable<K,​V>
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, java.util.Map<K,​V>
public class LinkedHashtable<K,​V>
extends java.util.Hashtable<K,​V>
Subclass of Hashtable that wraps a LinkedHashMap to provide predictable iteration order.

This is not a general purpose class but has been written because the protected members of Copy prohibited later revisions from using a more predictable collection.

Methods are synchronized to keep Hashtable's contract.

Since:
Ant 1.8.2
