1.106 LookupTable

Defined in namespace Smalltalk
Superclass: Dictionary
Category: Collections-Keyed

I am a more efficient variant of Dictionary that cannot be used as a pool dictionary of variables, as I don’t use Associations to store key-value pairs. I also cannot have nil as a key; if you need to be able to store nil as a key, use Dictionary instead. I use the object equality comparison message #= to determine equivalence of indices.
