Could someone explain why the "ToOne" and "ToMany" are the preferred semantics for the class names versus OneRelatedTo or RelatedToOne ? To me, "ToOne" feels like its describing the #directedMovies part. I guess it makes sense if you are looking in towards #director. cheers -ben On Fri, Feb 27, 20

Hello, Thanks for your suggestions. I have improved the naming and definition to this: Object subclass: #SlotExampleMovie slots: { #name. #year. #director => ToOneRelationSlot inverse: #directedMovies inClass: #SlotExamplePerson. #actors => ToManyRelationSlot inverse: #actedInMovies inClass: #Slo

Re: [Pharo-dev] Example implementation of associations with Slots in Pharo 4.0

Exactly :). In Fame, there is a FMMultivalueLink hierarchy that implement many to one and many to many relations. This implementation exists since before slots and now we should reimplement them with slots. It will make the code so much nicer :). Anyone interested in picking this up? Cheers, Dor

Re: [Pharo-dev] Example implementation of associations with Slots in Pharo 4.0

I haven't played with the relation example yet, but will real soon. Just some initial thoughts... I like RelationSlot. To me association seems one-way while a relation is two-way. btw, Is there some reason to not match the syntax of the often cited paper "Flexible Object Layout" ? I see one adv

Hi Jan Excellent! We know exactly whay we want slots and this is exactly for such kind of extensions. you may want to read the paper of Kasper Osterbye http://itu.dk/people/kasper/cv.htm R.11 Kasper Østerbye. Associations as a Language Construct. In Proceedings of TOOLS 29, Ed. Richard

[Pharo-dev] Example implementation of associations with Slots in Pharo 4.0

Today I experimented a little with the new Slots feature of Pharo 4.0. As an example I implemented support for associations/relationships. With it you can link two slots together so an update on one side will also update the other side of the association/relationship. I used these Movie and Perso
