Class XMLDecoder

java.lang.Object
  extended byjava.beans.XMLDecoder

public class XMLDecoder
extends Object

The XMLDecoder class is used to read XML documents created using the XMLEncoder and is used just like the ObjectInputStream. For example, one can use the following fragment to read the first object defined in an XML document written by the XMLEncoder class:

       XMLDecoder d = new XMLDecoder(
                          new BufferedInputStream(
                              new FileInputStream("Test.xml")));
       Object result = d.readObject();
       d.close();
