Interface XMLSerializable

All Superinterfaces:

Serializable

All Known Implementing Classes:

QName, Text, XMLBinding

public interface XMLSerializable
extends Serializable

This interface identifies classes supporting XML serialization (XML serialization is still possible for classes not implementing this interface through dynamic XMLBinding though).

Typically, classes implementing this interface have a protected static XMLFormat holding their default XML representation. For example:

     public final class Complex implements XMLSerializable {
       
         // Use the cartesien form for the default XML representation.        
         protected static final XMLFormat<Complex> XML = new XMLFormat<Complex>(Complex.class) {
             public Complex newInstance(Class<Complex> cls, InputElement xml) throws XMLStreamException {
                 return Complex.valueOf(xml.getAttribute("real", 0.0), 
                                        xml.getAttribute("imaginary", 0.0));
             }
             public void write(Complex complex, OutputElement xml) throws XMLStreamException {
                 xml.setAttribute("real", complex.getReal());
                 xml.setAttribute("imaginary", complex.getImaginary());
             }
             public void read(InputElement xml, Complex complex) {
                 // Immutable, deserialization occurs at creation, ref. newIntance(...) 
              }
         };
         ...
     }
