[cells-devel] Lots of instances, callback when particular instance changes

[Josip Gracin]

Hello!

I have the following class

	(defmodel switch (component)
	  ((pos :initarg :pos
		:initform (c-in :off)
		:accessor switch-position)))

and I've created lots of switches in a family and I can find them by 
name.  Is there any elegant way of establishing a dependency between one 
particular instance of switches and some code?  I mean, like a callback 
function to be called when the value of that switch changes?

If I use def-c-output on 'pos', it will get called whenever any of the 
switch instances sets it.

Thanks!
