Class XMLMarshaller

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

public class XMLMarshaller
extends java.lang.Object

Class used to marshal object to XML.

Create an XMLMarshaller from an XMLContext.
Code Sample
XMLContext context = new XMLContext("mySessionName");
XMLMarshaller marshaller = context.createMarshaller();


Objects can be marshalled to the following outputs:

• java.io.OutputStream
• java.io.Writer
• javax.xml.transform.Result
• org.w3c.dom.Node
• org.xml.sax.ContentHandler

Objects that can be marshalled are those which are mapped in the TopLink project associated with the XMLContext, and which are mapped to an XMLDescriptor that has a default root element specified.
