[Moose-dev] Re: MooseModel copy/deepCopy?

[Stéphane Ducasse]

I do not have the code at hand so I cannot really check.
Now if a model does not copy well itself (which I imagine) then we  
have to check carefully and implement the
postCopy method on the complete famix and moose entities so that we  
get a deepcopy instead of a shallow copy
  (have a look at my lectures, there are some slides on using postCopy  
in the hook and templates,
mathieu knows what I'm talking about so ask him.

The point of postcopy is that by default copy does a shallow copy and  
send a postCopy mesage.
You can redefine the postCopy to implement a deep recursive copy but  
this can be complex on
a graph like moose.

An alternate solution is to build a model walker and specialize it to  
perform copy (the copier could be
clever and be based on the metadescription). May be I would go for  
this solution.
