What would be a quantifiable definition of a lazy class (i.e. a class that does too little)? How little methods would a class need to have to qualify as lazy in your opinion? Would a class that only has a constructor, getters and setters qualify as lazy? Or would that count as a data-class?

I understand there are no hard-and-fast rules when it comes to this stuff, but I would be curious to hear different peoples opinions.
