Class XMLUnmarshaller

java.lang.Object
  org.eclipse.persistence.oxm.XMLUnmarshaller

public class XMLUnmarshaller
extends java.lang.Object

Class used to unmarshal XML to objects.

Create an XMLUnmarshaller from an XMLContext.
Code Sample
XMLContext context = new XMLContext("mySessionName");
XMLUnmarshaller unmarshaller = context.createUnmarshaller();


XML can be unmarshalled from the following inputs:

• java.io.File
• java.io.InputStream
• java.io.Reader
• java.net.URL
• javax.xml.transform.Source
• org.w3c.dom.Node
• org.xml.sax.InputSource

XML that can be unmarshalled is XML which has a root tag that corresponds to a default root element on an XMLDescriptor in the TopLink project associated with the XMLContext.
