JAXBElement<T> make the declared type T as a parameter to work with any class

Question

I got this code

private Object fooMethod(Node node, Class classOut)
  JAXBElement<MessageAcknowledgementType> root = unmarshallerjaxObject.unmarshal(node, MessageAcknowledgementType.class);

Since I am going to call the fooMethod with different class names, I want to specify into the JAXBElement the name of the class from the variable classOut, I have tried this but it doesn't work:

JAXBElement <classOut.getSimpleName()> root = unmarshallerjaxObject.unmarshal(node, classOut.getSimpleName()); //It doesn't work

Any idea about how to specify the class name into the JAXBElement?. Thank you!.

Answer 1

The simplest thing is:

private Object fooMethod(Node node, Class<?> classOut) {
    JAXBElement<?> root = unmarshallerjaxObject.unmarshal(node, classOut);
}

Answer 2

How about this:

Object obj = fooMethod(node, classout);

Define another method which will cast it to the appropriate type for you:

private <T> JAXBElement<T> getCast(Class<T> clazz, Object obj){
    return (JAXBElement<T>)obj;
}

     JAXBElement<Member> jaxbElement = getCast(SomeClass.class, obj);
