Synopsis

#include <rw/idenset.h>

typedef RWIdentitySet IdentitySet; // Smalltalk typedef

RWIdentitySet a;

Description 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

Public constructor

RWIdentitySet(size_t n = RWDEFAULT_CAPACITY);

Construct an empty identity set with n hashing buckets.

Public member functions 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
