Do anyone know of a set container class for Cocoa objects, that use
pointer semantics.
Like this:
NSMutableString * s1 = [@"Hello" mutableCopy], * s2 = [@"Hello"
mutableCopy];
Somesetclass *someSet = [[Somesetclass alloc]init];
[someSet add:s1];
[someSet add: s2];
// After these calls, someSet should contain 2 elements because s1 !
= s2 by pointer semantics
If you can require Leopard, take a look at NSHashTable.
Prior to Leopard, you can use the C interface for the same
functionality: http://developer.apple.com/documentation/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Functions/Reference/reference.html#/
