SYSML17 — NoBuffer has no effect if it is applied on an input pin

Open Closed All
  • Key: SYSML17-499
  • Status: closed  
  • Source: Airbus Group ( Mr. Yves Bernard)
  • Summary:

    According to the UML semantics for Activities execution, token will be placed on input pins of an action only when this action accept them. So there will be no case where token in a input pin will be "refused".

    As a consequence, applying the "NoBuffer" stereotype on an input pin will not have any effect, conversely to what the description sub clause of that stereotype suggests (in section 11.3.2.4).

    Proposal: clarify that "NoBuffer" should not be applied on input pins.

    No Buffer may actually has an effect on an input pin if that one is part of a structured node.
