使用泛型和ActiveJDBC模型

Question

I am trying to convert a list of records to some Java object (so, ActiveJDBC Model to another Java class), but I want to be able to call the same method for all my models and pass the Model type, something like:

private <M extends Model, T> List<T> getObjects(Class<M> modelType, Class<T> objectType) {
    List<T> records = new ArrayList<T>();
    M.findWith(new ModelListener<M>() {
        public void onModel(M row) {
            // Here I would convert the Model to my desired object and add it to the list of records
        }
    }, null);
    return records.isEmpty() ? null : records;
}

Which I would call like:

getObjects(MyModel.class, MyObject.class);

I get

Exception: failed to determine Model class name, are you sure models have been instrumented?

on M.findWith(...)

Any idea how to make it work?

Thanks!

you need to instrument models before you use them. Please, see http://javalite.io/instrumentation
