Hi sergio
what do you want to do?
Object subclass: #MyClass
instanceVarNames: 'dict'
MyClass>>initialize
[
super initialize.
dict := Dictionary new.
]
MyClass>>atKey: aKey put: aVal
[
dict at: aKey put: aVal
]
MyClass>>atKey: aKey
[
^ dict at: aKey
]
let you manage the key/val that you want?
Let me know if this answers your question.

is it possible to initialize a class with a dictionary? my first
thought would be to create a method like:
intializeWithDictionary: aDictionary
then, loop through the elements and do something like:
instVarNamed: key put: value
but the book says:
Caveat: Although these methods are useful for building development
tools, using them to develop conventional applications is a bad idea:
these reflective methods break the encapsulation boundary of your
objects and can there- fore make your code much harder to understand
and maintain.--
should i avoid this?
