The NSCountedSet class declares the programmatic interface to a mutable, unordered collection of indistinct objects. A counted set is also known as a bag.

Each distinct object inserted into an NSCountedSet object has a counter associated with it. NSCountedSetkeeps track of the number of times objects are inserted and requires that objects be removed the same number of times. Thus, there is only one instance of an object in an NSSet object even if the object has been added to the set multiple times. The count method defined by the superclass NSSet has special significance; it returns the number of distinct objects, not the total number of times objects are represented in the set. The NSSet and NSMutableSet classes are provided for static and dynamic sets (respectively) whose elements are distinct.

While NSCountedSet and CFBag are not toll-free bridged, they provide similar functionality.
