i mean more that maybe there are 1% that i can think of.
And still it is still pretty useable..
you just cant use generics for that case:
IDataProvider<Object> my = new IDataProvider<Object>()
{
private static final long serialVersionUID = 1L;
public void detach()
{
}
public int size()
{
return 0;
}
public IModel<Object> model(Object object)
{
Integer integer = (Integer)object;
return new YourModel<Object>(integer.toString());
}
public Iterator< ? extends Object> iterator(int first, int
count)
{
ArrayList<Integer> al = new ArrayList<Integer>();
return al.iterator();
}
};
works fine.
We dont discuss upfront all the kind of components what and how they should
be generified.
Many where done in 1 go and then see where it ends up by havinga few
Milestone builds where people can play with.
