I read the posts: - Very simple Java Dynamic Casting - java: how can i do dynamic casting of a variable from one type to another?
But it did not answer exactly what I was looking for. I need to create a method that creates a class from a XML inside a String. The XSD is created and I use JAXB with success to marshall/unmarshall the XML to Class and back. But this is too static. The code below is the actual code.
public static SaiRenovacao createClassFromString(String string,
Class Response) throws JAXBException {
SaiRenovacao _return = null;
StringReader reader = new StringReader(string);
JAXBContext jaxbContext = JAXBContext.newInstance(Response);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Object temp = unmarshaller.unmarshal(reader);
_return = (SaiRenovacao) temp;
return _return;
}
I wanna change this method. I need/would like to pass a Class by parameter 'Response' and my code must instantiate this Class [JAXBContext.newInstance(Response);] and unmarshall it and return the unmarshalled class - that is the class passed as parameter in Response - to the caller.
The way it is written I can only work with SaiRenovacao class.
If I change the implementation to I will get an obvious Exception because I can not resolve Response to a type. But this is the basic idea of what I need to do.
public static SaiRenovacao createClassFromString(String retorno,
Class Response) throws JAXBException {
SaiRenovacao _retorno = null;
StringReader reader = new StringReader(retorno);
JAXBContext jaxbContext = JAXBContext.newInstance(Response);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Object temp = unmarshaller.unmarshal(reader);
_retorno = (Response) temp;
return _retorno;
}
