I'm going to invent an awesome new software library. Would you like to use it,
for some amazing outputs?
Oh, except it uses EBCIDIC, not ASCII, for its source and inputs. You must
adjust all your tools to use it.
Would you like to use it now?

I try not to reject anything for one reason or another. The only thing
that would get me to reject a solution is finding a better one.
The question I hear all the time: "Is it possible to do x". The answer
is always "yes", sometimes it is "yes, but it would be ugly and take too
long". Working in a system without unit test tend to fall under the

Out of the two choices, I prefer the latter. If you make a new sub-
class of Geometry, you will have to change your createView function
(or make another one and have each work on a proper sub-set of
geometry objects.) This means that the createView(String type,
Geometry model) function is lying when it implies that it can work

If you know the subtype you want to create and you know the
subtype of the object that is returned by the Factory, why are you
using a Factory at all? Why not just construct an instance of Circle,
Box, or Triangle?
Alternatively, have the Factory return the appropriate Presenter
so that the code that invokes the Factory doesn't need to know about

So you have :
Box ISA Geometry ;
Circle ISA Geometry ;
// etc
View createView(Box) ;
View createView(Circle) ;
// etc
and you want to do the following :
<SomeType> model ;
View v = createView(model) ;
There are programming languages that, given #3 will select
the correct operation in #2 to execute (the process is called

Hi Daniel,
Let's say I have a bunch of model classes e.g. "Circle", "Box", "Triangle.
All classes are sub classes of bases class "Geometry" To edit certain
properties I have a properties view for each type. The specific view is
created by a factory that is passed a string to determine the type. Together

Not to me: Does Java still lack covariant return types?

danie...@earthlink.net (Daniel T.) — Thu, 24 Jul 2008 22:40:21 UT

Let me make sure I have this straight. You are passing in a string to
tell the factory what kind of sub-class to create, then you are having
to down-cast the object returned to the sub-class you know it is?
If that is the essence of what you are saying, then the problem with it
should be obvious.

downcasting and model view presenter

j.linxwei...@gmx.de (Jannis Linxweiler) — Thu, 24 Jul 2008 09:53:44 UT

hi ng,
i've got a general question concerning downcasts e.g. in context of the mvp
pattern.
i'd like to refer to the northwind starter kit example on codeplex.com:

in this example a navigation service is used to navigate between different
view. as i understand the navigation service works like a factory that loads

Said solutions are not complete without their unit tests.
I routinely reject systems - even up-and-coming ones with a lot of promise -
because they were not created under test, and they are impossible to test-first.

I would use man-hours. Not just the man-hours it takes to create each
solution, but the man-hours it takes to modify them.

comparing two software implementations

vijayakumar.subbu...@gmail.com (v4vijayakumar) — Wed, 23 Jul 2008 10:19:39 UT

how would you compare two software implementations, where one is based
on proper domain objects and abstractions, and another one hides
complexity by just providing a way to generate code that you have to
repeat through some kind of configuration files, etc.
many thanks in advance.
