It might be true to try and avoid wrappers in Python as it is a dynamic language and so would need to do all the stuff to check whether there is such a method when making a method call.
However Java being statically typed is much faster and typically one does not really get concerned about how many calls are made, I believe the performance drop (if any) is so small as to not be noticable (one could normally make greater optimisations elsewhere).

I disagree but OK. Do it however youlike. Any drop in efficiency would be completely inconsequencial. Wrapper classes are used all the time and are in fact an integral part of the "adapter" design pattern.

It seems to me simpler to just chose a different new name for the Semantics class, something like DocumentBase A wrapper class might also be less efficient.

Our Document class would have one member that would be something like: private java.xom.Document dom = new java.xom.Document(); and another member that would dhandle the Semantics: private Semantics semantics = new Semantics(); Also members for styles, actions, etc; whatever we need. This is the class that the views would interact with. So you might also have a member like: private View[] views; and methods like attachView and detachView. WordProcessor might just be a parent frame for the document, I think that's what it is mostly now. This is pseudo code so don't take it literally.

However renaming the Semantics class to Document will probably cause confusion, in part because XOM has a class with the same name. Perhpas it could be renamed Model. Maybe someone has a better idea. It won't be the first time I've had to rename things. Thanks, John -- John J.
