in thread Short Refactoring Tip: let the object do it for you

  1. You are correct that reducing the need for "can you do this? yes? then do it" was what I was trying to say. This was the problem with the original solution.
  2. When I think about it (why always AFTER I post?!) you are correct in saying that I am misrepresenting encapsulation. Query methods are a tool to defend encapsulation. Getters break encapsulation. Query methods (any methods actually) increase coupling- of course the ultimately independent object has no methods, and is ultimately useless. What I was trying to say was that in our example (although it is sketchy) we can decrease coupling by dispensing with the query methods.

So a predicate function is a boolean query method.
