Hi Mariano,
This presents me with a big challenge, then. I read the docs and
explored the code and the only other aspect not mentioned, beyond
instance creation (#fuelNew #fuelNew:) and postMaterialization
(#fuelAfterMaterialization), is migrations. However, migration only
allows for instanceVar mappings, no code blocks.
What do you mean that migrations only allows instVar mappings , and no
code blocks? I mean, what do you mean by code blocks?
We also support class renames. This is here:

Well, my pics will demonstrate. I am interested in doing more than
mappping ivars or a class rename. I want to do a total substitution,
then a further substitution on the receiving, import side:
Vat1: anObject (Class A) ---> On wire: desc (Descriptor) ---> Vat2:
aProxy (Class FarERef)
A desc is substituted for a PassByProxy object, then a FarERef is
substituted for the desc.
#fuelAccept: is a serialization side method.
If Fuel supports substitution on serialization, I don't understand
why no substitution support on materialization.
There was a reason, which I cannot remember completely. Maybe Martin or
Max can remember.
It seems your focus was pickling to disk then back. My focus is
distributed proxy graphs, which has different use cases.
I am definitely going to use the world-class Fuel binary
serialization system. However, I find myself needing to extend Fuel
to support substitution on materialization. Perhaps the solution is
a custom decoder.
I have made custom clusters for example for my Ghost proxies of Marea
system. It was a perfect example of how I could extent Fuel besides the
common hooks. Fuel provides many places for extending , like clusters,
analyzer, etc
Right on, exactly! Could you tell me more about your Ghost proxies and
Marea, please? As well, could you mention how you select a custom
cluster on the serialization side?
thanks so much ^^
Robert
No, a bit more. It looks like I need a new
FLSubstitutePointerObjectCluster, write them on serialization with
the substitute, then do unsubstitution on materialization, since the
cluster controls materialization and not the decoder.
Does this approach seem sound to you, from a you know architecture
and design approach?
There was an issue. Hope other can remember. If not, I will try to
explan what I remember tomorrow.
thanks so much ^^

No, unfortunately, as far as I can remember, we do not have
that. There
are another hooks you may use but only in certain scenarios
(#fuelNew,
#fuelAfterMaterialization, global sends, etc). But everything is
listed
in
http://rmod.inria.fr/web/software/Fuel/Version1.9/Documentation/CustomizingGraph
so if you didn't find anything of help in there there are chances
there isn't anything.

Every extra source helps, thank you. I see how to do
non-stream substitutions on materializations, but the
documentation did not indicate a way to do non-stream
substitutions on serialization. Is it possible?
I don’t understand what you mean by “non-stream”. Could
you give
an example?
thanks,

Hi Robert,
As for the documentation, you have LOTS of

have the chapter
Torsten pasted, you have this documentation:

Let us know how it goes,
