Hi,
I want to manage and control access to several important attributes in
a class and override the behaviour of some of them in various
subclasses.
Below is a stripped version of how I've implemented this in my current
bit of work.
It works well enough, but I can't help feeling there a cleaner more
readable way of doing this (with less duplication, etc).
Is this as good as it gets or can this be refined and improved
especially if I was to add in a couple more attributes some fairly
complex over-ride logic?
(snip code)
Remember that properties have nothing magical - they're just one
possible (and very handy) way to use the descriptor protocol to
implement computed attributes. If you have to resort to any non-obvious
trick or just too much boilerplate code with properties, then it's
probably time to implementent your own custom descriptor object.
