Hi, can someone explain to me the philosophy/principles behind Core
Foundation? I'm just having a hard time seeing the overall
relationship between Carbon, Core Foundation, and Cocoa.
A few (stupid) questions I have are:
+ Why was Core Foundation invented?
+ What did developers use BEFORE Core Foundation, back in the NEXTSTEP
days? There was no Core Foundation back then, correct? Everything was
pure Obj-C/Cocoa?
+ When Apple and NeXT merged, the Carbon and Cocoa (before they got
those names) APIs needed merging? And so a common base was created?
And it is Core Foundation?
Below is my semi-understanding (that's why they're questions, not
statements) of things, and I would greatly appreciate corrections to
it:
+ Cocoa is the current evolution of NEXTSTEP and (still) based on Objective-C?
+ Carbon is the current, but deprecated evolution of the C++ based
APIs from Mac OS 8 and 9?
The rest are shots in the dark. Please correct me:
+ Core Foundation is C-based glue code between Carbon and Cocoa?
+ Core Foundation is C-based glue code between Carbon and the underlying OS?
+ Core Foundation is C-based glue code that allows Carbon apps to have
Aqua GUIs?
+ Core Foundation is ???? I'm asking.
All of this may seem like idle chatter to the experts, but answering
them goes a long way towards understanding what the docs are talking
about, and what others mean when discussing OS X development.
Thanks,
