1.62 Dictionary

Defined in namespace Smalltalk
Superclass: HashedCollection
Category: Collections-Keyed
I implement a dictionary, which is an object that is indexed by unique objects (typcially instances of Symbol), and associates another object with that index. I use the equality operator = to determine equality of indices.

In almost all places where you would use a plain Dictionary, a LookupTable would be more efficient; see LookupTable's comment before you use it. I do have a couple of special features that are useful in certain special cases.
