Trying out some older code and I've come across an IdentityDictionary. From what I know NSDictionary uses equality, not identity to compare Objects. Judging by it's use it seems I would need a mutable IdentityDictionary anyway?
I've read two threads on this and it seems to be quite difficult to do, Class clusters, hash functions and so on.
Does NSDictionary's objectForKey: rely on identity or equality
Implementing -hash / -isEqual: / -isEqualTo
How would one go about doing this?
