typedef RWIdentitySet IdentitySet; // Smalltalk typedef
RWIdentitySet a;

The class RWIdentitySet is similar to class RWSet except that items are found by requiring that they be identical (i.e., have the same address) as the key, rather than being equal (i.e., test true for isEqual()).

The iterator for this class is RWSetIterator.

Polymorphic

RWIdentitySet(size_t n = RWDEFAULT_CAPACITY);

Construct an empty identity set with n hashing buckets.

The user interface to this class is identical to class RWSet and is not reproduced here. The only difference between the classes is that keys are found on the basis of identity rather than equality, and that the virtual function isA() returns __RWIDENTITYSET, the ClassId for RWIdentitySet.
