[mdt-papyrus.dev] About OCL for specifying and calculating derivation ru

[GERARD Sebastien <Sebastien.GERARD@xxxxxx>]

Hi,

 

Does someone know if it possible to use (as explained here ), OCL in Papyrus profile definition to specify a derivation rule of a derived property of a stereotype ? And in that case, when applyng the profile embedding the OCL rules, will the derived property value calculated automatically ?

 

Here is an example of profile :

 

 

Here is the derivation rule specification for the commonMeaning property:

 

The commonMeaning attribute is a derived property subetting the meanings attribute. The derivation rule shall be the following: the value of the commonMeaning attribute is calculated as being the Definition model element (i.e., owned comments stereotyped with <<Definition>> and annotating the owner element, in that case the Term itself). 

 

And here is an OCL rule, I tried to write to implement the derivation rule of the commonMeaning property:

 

self.commonMeaning: Definition derive:

self.base_Class.ownedComment-> select ( oc | oc.isStereotypeApplied(Definition) and oc.isCommon = true)

 

Thanks for helping,

Best,

Sébastien.
