Need Help??

in reply to Access to single object from multiple other objects

Thanks everyone for the suggestions!

Looks like passing it to the objects as an argument is the preffered solution. My only issue with that is that I have a relatively large object hierarchy, with something similar to the following objects:

A instantiates B and C
B instantiates D
D instantiates E
[...]

So now if E needs access to the config module I'll have to pass it all the way down.

Yes, passing is slightly more typing, but if you don't, then you're accessing a global variable -- which is worse? The following might shed a little light

Why Singletons are Evil - Being Scott Densmore - Site Home - MSDN Blogs , Use your singletons wisely ; Know when to use singletons, and when to leave them behind

So a global app configuration is common use of a singleton ... I've used it, I've seen it used ... I don't really have an informed opinion :)
