Instance Creation Pattern

I've seen a lot of code like:
MyAbstractSuperclass>>subclassInstanceAppropriateFor: anObject
Which returns an instance of a subclass specialized for anObject. I don't see how I would integrate this type of code with magritte. Am I missing something obvious?

Thanks!

I don't understand the question.

Thanks for the reply. What I was pondering was the apparent mismatch between the memento way of object creation and class-side instance creation methods which need some information passed to them to determine which subclass to actually return an instance of.


I guess what I need is something like:
MySuperclass new asMorph
        addButtons;
        addWindow;
        onAnswer: [ :e | subclassInstance := MySuperclass instanceCreationMessage: e releventInformation ];
        openInWorld.
