Class XMLUnmarshallerHandler
- java.lang.Object
-
- org.eclipse.persistence.platform.xml.SAXDocumentBuilder
-
- org.eclipse.persistence.oxm.XMLUnmarshallerHandler
-
- All Implemented Interfaces:
org.eclipse.persistence.internal.oxm.record.ExtendedContentHandler,org.eclipse.persistence.internal.oxm.UnmarshallerHandler,org.xml.sax.ContentHandler,org.xml.sax.ext.LexicalHandler
public class XMLUnmarshallerHandler extends SAXDocumentBuilder implements org.eclipse.persistence.internal.oxm.UnmarshallerHandler
Class used to unmarshal SAX events to objects.
Create an XMLUnmarshallerHandler from an XMLUnmarshaller.
Code Sample
XMLContext context = new XMLContext("mySessionName");
XMLUnmarshaller unmarshaller = context.createUnmarshaller();
XMLUnmarshallerHandler unmarshallerHandler = unmarshaller.getUnmarshallerHandler();
Use the UnmarshallerHandler with an XMLReader
Code Sample
SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
saxParserFactory.setNamespaceAware(true);
SAXParser saxParser = saxParserFactory.newSAXParser();
XMLReader xmlReader = saxParser.getXMLReader();
xmlReader.setContentHandler(xmlUnmarshallerHandler);
FileInputStream inputStream = new FileInputStream("MyFile.xml");
InputSource inputSource = new InputSource(inputStream);
xmlReader.parse(inputSource);
Object result = xmlUnmarshallerHandler.getResult();
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.
