EswShadowClass before 1996 history

[jp.]

Hi.
I found that the class EswShadowClass has the following method (in Application Swapper):

Code: Select all

fixForMetaclassFor: aLoadingReplacer
   "Fixes the receiver so that it represents a primaryInstance of a Metaclass. If receiver is
    already a EswShadowClass, receiver has already been fixed, and caches in field %description the
    replacement in the image. Return it."

   ^self getCachedImageReplacement

and the following method (in Application SstSwaperBRMarshaling):

Code: Select all

sstFixUpDuringLoadUsing: replacer
   "Fixes the receiver so that it represents a primaryInstance of a Metaclass. If receiver is
   already a EswShadowClass, receiver has already been fixed, and caches in field %description the
   replacement in the image. Return it."

   ^self getCachedImageReplacement

The first one is from 1996 and the second one from 1997.

Does anybody know why the second one was created, or if it was created before the first one?

Thanks

Juan Pablo -

While the methods intersect on EswShadowClass, their other implementations do not intersect (i.e., they are not implemented on the same classes). So, EswShadowClass>>sstFixupDuringLoadUsing: could have forwarded its invocation to EswShadowClass>>fixForMethaclassFor:, but it could not have been replaced by EswShadowClass>>fixForMetaclassFor:.
