LinkedHashtable (Apache Ant API)

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
