[jdom-interest] Class generator

[Rolf]

Hi Alexandre.

Thank you for your feedback. It's nice when people respond the way you have.

I have some observations, and a question....

First the questions, in an earlier mail you indicated that you are using 
Java 1.2.1. Do you have this running under Java 1.2.1? Are you using 
JDOM 1.1.2?

Then the observations....

Just out of interest (and I know that the 'cars2java' example may be a 
massive simplification), but have you considered simply extending the 
JDOM classes to get what you want? You may be able to eliminate a 
complex 'model'. It may create other issues, but, you may come up with a 
simpler (and perhaps better) solution.

For example, you could declare the class 'Car' to be:

public class Car extends org.jdom.Element {

     public Car(String brandname) {
         super("Car");
         setBrand(brandname);
     }

     public void setBrand(String brandname) {
         Element brand = getChild("Brand");
         if (brand == null) {
             brand = new Element("Brand");
             // add brand at the beginning of our content....
             addContent(0, brand);
         }
         brand.setText(brandname);
     }

     public String getBrand() {
         Element brand = getChild("Brand");
         if (brand == null) {
             return "";
         }
         return brand.getText();
     }

     ......

}

Once you have defined 'Car' to extend the JDOM Element, you can create 
Car instances, and add them directly to a root element:

Element cars = new Element("Cars");
Car renault = new Car("renault");
renault.setColorRGB("red", "FF0000");
cars.addContent(renault);

xmlout.output(System.out, cars);


Just some thoughts.
