    • refreshVisuals

      protected void refreshVisuals()
      This method is called, whenever the data of the underlying ModelObject changes. It must update the figures to display the changed data. Sub-classes will nearly always overwrite this method.

      By default this method takes care to update the labels of the attributes (if existing) and to update the arrows at the connection-endpoints, so sub-classes should call super.refreshVisuals().

      Overrides:
      refreshVisuals in class org.eclipse.gef.editparts.AbstractEditPart
      See Also:
      • AbstractEditPart.refreshVisuals()

      Returns:
      the model children

    • getModelSourceConnections
