UML14 — UML RTF 1.4 Issue: State constraint on host object

  • Key: UML14-987
  • Legacy Issue Number: 3274
  • Status: closed  
  • Source: NIST ( Conrad Bock)
  • Summary:

    States currently do not model the conditions required for an
    object to be in a particular state. A constraint note can be
    linked to a state, but there is no specification of when the
    constraint should be tested. It could be tested when the object
    enters the state, leaves the state, or at any other time. Even if
    this were unambiguous, the consequence of violating the constraint
    is not defined, namely, to transition the machine to a state that
    has a constraint satisfied by the object. This might be modeled
    as a change-event trigger on an exiting transition, but it would
    be redundant with the constraint recorded on the state and with
    triggers on other transitions leaving the state, thereby impairing
    maintainability.
