Open Closed All
  • Key: UMLR-108
  • Legacy Issue Number: 10600
  • Status: open  
  • Source: Simula Research Laboratory ( Dr. Bran Selic)
  • Summary:

    The UML Abstractions concept should include a constraint that a graph involving Abstraction relationships should be acyclic; i.e. an <element type> cannot be both a transitively higher level of abstraction and transitively lower level of abstraction of the same <element type>.

    not self.getHigherLevelAbstractions()->includes(self)
