All Implemented Interfaces:

Serializable, Cloneable

public class XMLDescriptor
extends ClassDescriptor

Use an XML project for nontransactional, nonpersistent (in-memory) conversions between Java objects and XML documents. An XMLDescriptor is a set of mappings that describe how an objects's data is to be represented in an XML document. XML descriptors describe Java objects that you map to simple and complex types defined by an XML schema document (XSD). Using XML descriptors in an EclipseLink XML project, you can configure XML mappings.
