@Laiv I like the example you gave but is it possible that isEmpty() method of BaseBO class is not abstract and instead dynamically go through all the fields of the class and evaluate the same expression something like return field1 == null && field2 == null && ... fieldn == null? This way I dont have to define isEmpty() method in sub classes. Example: in Location class the isEmpty() method will evaluate to return description == null && active == null.
