UML22 — Sending a signal after a delay

  • Key: UML22-475
  • Legacy Issue Number: 4937
  • Status: closed  
  • Source: Object Management Group ( Stephen Mellor)
  • Summary:

    Sending a signal after a delay

  • Reported: XMI 1.3 — Tue, 5 Mar 2002 05:00 GMT
  • Disposition: Resolved — UML 2.1.2
  • Disposition Summary:

    The feature requested is already supported in UML 2.1: Precede an action by an AcceptEventAction, where the latter references a trigger that refers to a TimeEvent. Thus, for example, if you have a sequence of an AcceptEventAction with a TimeEvent specifyinig the desired delay and a SendSignalAction, then the signal will not be sent until the delay has passed. Note that this feature is extremely generic, probably giving the user even too much support (you can define a statemachine purely with actions, if there are not proper constraint placed on the events allowed in the AcceptEventAction).
