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:

Serializable, Cloneable, Map<K,V>

public class LinkedHashtable<K,V>
extends 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
