Get “Class” object from generic type T

Question

I want to make generic function that return Object representation of XML document (using JAXB). I need to pass \"class\" object to JAXBContext constructor, but how I can get it

Answer 1

Pass the class object instead and it's easy.

public  T readXmlToObject(String xmlFileName, Class  jaxbClass) {
       JAXBContext context = JAXBContext.newInstance( jaxbClass ); // T.class - here error, how to get it?
       Object o = context.createUnmarshaller().unmarshal( new File( xmlFileName ) );
       return jaxbClass.cast( o );
}

The idea here is that since you can't extract the type parameter from the object, you have to do it the other way around: start with the class and then manipulate the object to match the type parameter.
