      @CheckForNull public static Element getClientElement(InstanceSpecification link)
      Return client element from InstanceSpecification (link) Custom way to get relationship info from Link
      Parameters:
      link - link
      Returns:
      Client element

    • getSupplierElement

      @CheckForNull public static Element getSupplierElement(InstanceSpecification link)
      Returns supplier element from InstanceSpecification (Link)
      Parameters:
      link - link

      supplier element

    • setConnectedInstance

      public static void setConnectedInstance(InstanceSpecification link, Element value, Property memberEnd)

    • synchronizeLinkSlotValuesByType

      public static void synchronizeLinkSlotValuesByType(InstanceSpecification link)
      During link end change, sometimes opposite side instance values are defined, and they need to be switched
      Parameters:
      link - synchronized link

    • hasCorrectClassifier

      public static 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

      public static void moveSlotReference(Property stableEnd, Property movedEnd, InstanceSpecification source, InstanceSpecification destination, InstanceSpecification stableInstance)
      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)
      Parameters:
      link - link
      value - new client value

    • setLinkSupplierElement

      public static void setLinkSupplierElement(InstanceSpecification link, Element value)
      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

    • isLink

      public static boolean isLink(@CheckForNull InstanceSpecification instance)
      Checks if InstanceSpecification is Link.
      Parameters:
      instance - instance to check
      Returns:
      true if it is Link element - it has Association as classifier or has a Link symbol in diagram

    • getAssociationsOfLink

      public static Collection<Association> getAssociationsOfLink(InstanceSpecification instance)
      Gets Association classifier from InstanceSpecification, if exists.
      Parameters:
      instance - Link instance
      Returns:
      Associations or empty collection

    • findRelatedLinks

      public static Collection<InstanceSpecification> findRelatedLinks(@CheckForNull Slot slot)
      If slot value corresponds to connected instance, returns link which connects two instances.
