FAQs

• There’s a lot of repetition between FloatHolder and FloatViewHolder, why can’t we combine them?

  • In hindsight, we could define a class FloatHolderAPI<T> that is templated on the type of Float that will hold it. FloatModel would always derive from FloatHolderAPI<Float> whereas FloatViewModel would derive from FloatHolderAPI<Float> or FloatHolderAPI<const Float> depending on the const-ness of the type argument to FloatViewModel. The holder classes were already written when this realization occurred, so it was not worth the effort to refactor them.
