UML14 — UML RTF 1.4 Issue: Guard condition in collaborations poorly named.

  • Key: UML14-1003
  • Legacy Issue Number: 3294
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    [p 125, notation] predecessor guard-condition
    sequence-expression return-value := message-name

    The descriptions after this imply that "predecessor" and "guard
    condition" are the same:

    [p 125, notation] The meaning is that the Message is not
    enabled until all of the communications whose sequence
    numbers appear in the list have occurred (once the
    communication has occurred the guard remains
    satisfied). Therefore, the guard condition represents a
    synchronization of threads.

    It's confusing the have two names for the same thing. I
    thought on first glance that some bracketed notation as in
    state machine were supported at this position in the label, but
    that is in the recurrence part of sequence expressions.
