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
