So, the proper implementation would be the following? (now uses CommentReference)
"Used by a message set browser to access the list view information."
| messageList |
messageList := OrderedCollection new.
changeRecords associationsDo: [:clAssoc | | classNameInParts classNameInFull |
classNameInFull := clAssoc key asString.
classNameInParts := classNameInFull findTokens: ' '.
(clAssoc value allChangeTypes includes: #comment) ifTrue:
(CommentReference class: (Smalltalk globals classNamed: classNameInParts first))].
clAssoc value methodChangeTypes associationsDo: [:mAssoc |
(#(remove addedThenRemoved) includes: mAssoc value) ifFalse:
setClassSymbol: classNameInParts first asSymbol
classIsMeta: classNameInParts size > 1
methodSymbol: mAssoc key
stringVersion: classNameInFull, ' ' , mAssoc key)]]].
^ messageList asArray sort
Well well, thats not really nice. CommentReference is not entirely polymorphic to MethodReference.
It should have
^ self actualClass category
to be able to move #topLevelPackageName from MethodReference to SourceReference. Every piece of source is part of some package, no? Including the class comments. Well, at least it breaks our file-out mechanism if that is not true.
