Description

The list of methods to do XML JAXB Unmarshaller are organized into topic(s).

Method

Tunmarshal(Class clz, File file)
unmarshal 
Unmarshaller u = _jaxbContexts.get(clz).createUnmarshaller();
return clz.cast(u.unmarshal(file));
Objectunmarshal(File f)
Unmarshals a file. 
return unmar.unmarshal(f);
Objectunmarshal(final Class clazz, String json)
unmarshal 
Gson gson = new Gson();
return gson.fromJson(json, clazz);
Tunmarshal(final String xml, Class clazz, InputStream inputSchema)
Unmarshalls the XML string given the JaxB class. 
try {
    JAXBContext ctxt = JAXBContext.newInstance(clazz);
    Unmarshaller u = ctxt.createUnmarshaller();
    if (inputSchema != null) {
        if (inputSchema != null) {
            SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
            Schema schema = sf.newSchema(new StreamSource(inputSchema));
            u.setSchema(schema);
...
Tunmarshal(final String xml, final Class clazz)
JAXBContext.newInstance(..) is a slow operation. 
return (T) unmarshal(JAXBContext.newInstance(clazz), xml);
Objectunmarshal(InputSource inputSource, Class clazz)
Unmarshal. 
JAXBContext jc = JAXBContext.newInstance(clazz);
Unmarshaller u = jc.createUnmarshaller();
ValidationEventCollector vec = new ValidationEventCollector();
u.setEventHandler(vec);
Object o1 = u.unmarshal(inputSource);
return o1;
Tunmarshal(InputStream content, Class expectedType)

Unmarshal XML data from InputStream by expectedType and return the resulting content tree.

return unmarshal(new StreamSource(content), expectedType);
Tunmarshal(InputStream in, Class... boundClasses)
unmarshal 
try {
    Unmarshaller u = JAXBContext.newInstance(boundClasses).createUnmarshaller();
    return (T) u.unmarshal(in);
} catch (Exception ex) {
return null;
Tunmarshal(InputStream inputStream, Class entityClass)
Unmarshal XML data from the specified file and return the resulting object. 
JAXBContext jaxbContext = JAXBContext.newInstance(entityClass);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
T document = (T) jaxbUnmarshaller.unmarshal(inputStream);
return document;
Tunmarshal(InputStream inputStream, Class type)
Attempts to unmarshal an XML document from an InputStream. 
JAXBContext jaxbContext = JAXBContext.newInstance(type.getPackage().getName());
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
@SuppressWarnings("unchecked")
JAXBElement<T> jaxbElement = (JAXBElement<T>) unmarshaller.unmarshal(inputStream);
return jaxbElement.getValue();
