Thx. Thats exactly what I was looking for. The key part being "self isInitializer" where...

�� isInitializer

�� ^ selector = #initialize and: [classIsMeta]

Now I also see "self isExternalStructureFieldDefinition"

�� "Postloading of FFI fields. This code will be called when loading FFI structures that are not by default in the image."

Could something similar be done like "self isEnumDecl" ?�� It would be a minor improvement to not have write up in blog posts that��

MyFFIExternalEnumeration needs a class-side #initialize simply to do "self��initializeEnumeration"��

when having #enumDecl is a strong convention and indicator that intialization is required.

Or is that starting to load up with too many implicit initializations?

Alternatively,��what consideration has been given to pragmas for class initialization?

For example this seems more self contained and explicit....

�� MyFFIExternalEnumeration class >> enumDecl

�� <classInitialization: #initializeEnumeration>

�� ^ #( EnumA�� 1�� EnumB 2)

Hi,

the #initialize message is sent only to the classes that implement this method. In *.st files it is an explicit call, Monticello does it slightly smarter way, see��MCMethodDefinition>>#postloadOver:

When MyClass is loaded, #initialize is sent to it.�� Typically the class-side>>initialize should not call "super initialize" to avoid re-initializing the superclaass, but what if MyClass doesn't implement #initialize?�� Does the message fall through to the superclass, or is #initialize only sent if MyClass implements it?

FFIExternalEnumeration subclass MyEnumeration needs to be sent #initializeEnumeration when it is loaded.�� We have...

�� FFIExternalEnustmeration>>#initialize��
self initializeEnumeration

so is MyEnumeration *required* to implement its own MyEnumeration>>#initialize, or can it rely FFIExternalEnustmeration>>#initialize.�� I believe it is the former, but just wanted to confirm my understanding.
