Class 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
