        public static java.util.Collection<Classifier> hasCorrectClassifier​(InstanceSpecification link)
        Checks if link is connected to instances according to its association; Check is done by checking if instance values has classifiers same as association member end types
        Parameters:
        link - link (only links are analyzed)
        Returns:
        empty list if OK, wrong classifiers if not

      • moveSlotReference

        Updates slots when link ends were changed
        Parameters:
        stableEnd - association member end, which is representing link end does not move
        movedEnd - association member end, which is representing link end moves
        source - disconnected instance
        destination - connected instance
        stableInstance - stable instance (which end was not changed)

      • setLinkClientElement

        public static void setLinkClientElement​(InstanceSpecification link,
                                        Element value)
        Sets client element from InstanceSpecification (link)

        Sets supplier element for InstanceSpecification (link) Custom way to make Link behavior as relationship - add client and supplier info to the slots
        Parameters:
        link - link
        value - new supplier value
