New subject: certainly a stupid question

9 Oct 2008

...
  what is FMMultivalueLink? 
A subclass of Collection.

...
  parentClass: aType
 	parentClass := FMMultivalueLink on: self
 					update: #attributes
 					from: self parentClass
 					to: aType
 	parentClass set: aType

 I'm probably too stupid to understand but let us try. 
This is a class-method but not a constructor!

#on:update:from:to: updates the opposite end of a link
#on:opposite: *creates* a new link instance

...
  I do not understand why at the metamodel level I need
to have in the
 runtime objects of the metametamodel. 
It is not, metametamodel classes start with 'FM3'.

...
  Long long time ago I did a stupid code generator that
took a stupid
 MMModel and generated plain code for the metamodel.
 Why this is not like that  with FAMIX30
 in the latest version?
 why do we trade space **and** speed for a meta stuff? 
You dont trade.

Space is the same -> a link consist of a collection on one side and  
of a naked inst var on the other side.
Speed is the same -> it does the minimal set of operations in order  
to update both ends.

...
  So do I have to code a code generator? 
No, Fame offers a ready-to-use code generator.

...
  Or just replace all the FMMultivalueLink myself?

No need.

...
  I'm confused I thought that the new FAME was
better.
