Adaptive Magritte Trait
Locked

Quoting from http://sdmeta.gforge.inria.fr/Teaching/Lille/0910-MetaModelisation/07-08-Cours43-DescribedBy-Reng07aMagritte.pdf section 4.1:
The Adaptive- Model has two instance variables, the first being used to refer to the descriptions of the instance and the other one to keep a list of the actual values of the model. Transforming the class of the adaptive model into a Trait [18] allows us turn any existing class into an adaptive model and to combine the descriptions defined in the class with the ones provided by the instance. I cannot find this trait. Does it exist in magritte? I see MAAdaptiveModel, but I am indeed trying to add adaptivity to a class, and am struggling with it _______________________________________________ Magritte, Pier and Related Tools ... https://www.list.inf.unibe.ch/listinfo/smallwiki |

Well, I think I at least figured out how to implement it. My issue was how to detect whether a given description is a regular one, or an adaptive one, in the implementation of #readUsing:. However, I then remembered that PRComponent already needs to do this, and so I looked at it’s code. It does
(self basicMagritteDescription includes: aDescription) That still leaves the question though, does this trait version of MAAdaptiveModel exist? > On 11 Sep 2016, at 19:19, Tapple Gao <[hidden email]> wrote: > > Quoting from http://sdmeta.gforge.inria.fr/Teaching/Lille/0910-MetaModelisation/07-08-Cours43-DescribedBy-Reng07aMagritte.pdf section 4.1: > > The Adaptive- Model has two instance variables, the first being used to refer to the descriptions of the instance and the other one to keep a list of the actual values of the model.

I'd recommend checking

Hi,
I have not read the article, but from what you describe I think Magritte already has an adaptive model, although it is not very explicit. All objects can be asked for a magritte description on demand, and based on this description the components are generated. The components usually use a cache for the values, where the values are read from and stored into when the user makes changes. So, the components have a reference the description of the model and to the actual values of the model.
