Hi All,
I find myself often having to define pure marker interfaces for each
class that I define, purely so I can register adapters for objects of
that class.
How do people feel about:
- being able to register an adapter as follows:
adapter
for=.myclasses.MyClass

real reasons for why this is bad.
Well it removes the possibility of switching out the class, which
begs the question why you would have an adapter in the first place.

Sorry about the premature sending, I don't know what button I pressed...
Here we go again:
So instead of making a marker interface, which is two lines of code,
and two registrations, a total of six lines (with the imports), you
have an extra ZCML registration statement, which is three lines of

Sure, but with the marker interface you need only one. You need one
for each class, in your example, thats two. So

I think it is a fine idea. That's why it has been supported for
a long time. You can register adapters and views (which, of course
are adapters) for classes as well

Why does your class not have a (non-marker) interface in the first place?

Hi,
I'll be around at PyCon 2007 and I plan to have a Zope 3.4 sprint there.
I've added a wiki page to the PyCon 2007 wiki and everybody is invited
to join me:

The use of interfaces as documentation and as formalisms for expressing a
class' functionality (in adapters, utilities etc) is one of the benefits
that Zope 3 introduces. I

I plan to do some bugfixing in zope.formlib and zope.app.form. This is

SH to know exactly what Zope is storing. FileStorage makes that fairly hard.
There is half-baked solution at z3c.zodbbrowser.
Without knowing your exact requirements, I suggest you take a look.
