According to their website, they plan on releasing JDK 5 final in
the fourth quarter of 2005.
I believe you guys said you'd hold off on Java 5 support until IBM
had a version out. Now that this is near please consider what changes
you plan on making. Concurrency libraries come to mind, as do type-safe
enums. Anything else?
Generics should help to avoid a lot of castings. I would like to see
generics on models. The model would still be a clean Facade while
retaining type safety for users.
interface IModel<T> {
T getModelObject();
}
class Component<T> {
IModel<T> getModel() ...
T getModelObject() ...
}
abstract class ListView<S> extends Component<List<S>> {
public ListView(String id, IModel<List<S>> model)
public onRequest() {
for (S s : getModelObject()) {
Item<S> m = newItem();
populateItem(m);
}
}
public abstract populateItem(Item<S> item);
}
usage:
ArrayList<String> l = new ArrayList<String>();
l.add("a");
l.add("b");
new ListView<String>("id", l) {
public populateItem(Item<String> item) {
item.add(new Label("label", item.getModelObject()));
}
};
