I'm not sure what you mean by a "wrapper" here. Is this just a custom
Objective-C class? If so, then you can just test using Objective-C
introspection methods, like -isKindOfClass:
if([array isKindOfClass:[YourPascalWrapperClass class]])
...it's your wrapper...
else
...don't do anything funny...
The "wrapper" is a Pascal class that controls an Objective-C object,
so we can't use introspection on it. The plan was to determine if a
pointer was a CFType then use it directly with the Objective-C
runtime, otherwise dereference it to get the Objective-C object and
use that instead. This is all a measure so users don't have to make
this choice themselves. If I could differentiate a Pascal object from
a plain Pointer it would serve the same purpose but I thought a
NSArray and CFArray were testable. I think it's safe to say this test
can not be performed based on what Greg Parker said.
