The execution model shall provide a flexible mechanism for instantiation of composite structures

  • Prototype implementation available
  • Based on an extension of CallOperationActionAction::doAction, and introduction of a new semantic strategy: CS_ConstructStrategy
    • If the called Operation is a «Create» operation, and it has no method, then the CS_ConstructStrategy is used to construct the composite structure instance
  • Using this prototype implementation, the Test Suite for instantiation of composite structures passes
  • Issues:
    • How to properly determine that an operation is a «create» operation?
      • Currently, the solution is implementation specific (Eclipse UML2)
    • How do we manage operation dispatching (i.e., a parent class has a constructor operation with a method. Should we execute it before performing default construction?)
  • TODOs:
    • When instantiating values for parts, the default construction strategy is systematically applied.
      • It should be used only if the type of the part has a «create» operation, and this operation has no method. If it is not the case, construction should follow conventions of the Alf to fUML mapping for an instance creation expression.
    • Start classifier behavior of classes constructed for parts
    • Account for default values when instantiating values for parts
