SYSML17 — SysML 1.2 Issues: Optional with streaming

  • Key: SYSML17-47
  • Legacy Issue Number: 15299
  • Status: open  
  • Source: Change Vision ( Michael Chonoles)
  • Summary:

    Sysm 1.2 Optional with «streaming»

    Page 92

    11.3.2.6 Optional

    Does optional on an input mean optional to start the activity or optional for the activity to finish? Consider an «optional» streaming input.

    Does optional on an output mean optional to appear at the end of the activity or optional for it ever to appear? Consider an «optional» streaming output..

    We need to have all the possibilities for streaming; it probably should have two multiplicities for each streaming parameter

    Starting Multiplicity: number of tokens that must appear for the activity to start

    Total Multiplicity: number of tokens that must appear over the lifetime of the activity

    Ending Multiplicity: number of tokens that must appear at the end of the activity

    Total Multiplicity: number of tokens that must appear over the lifetime of the activity
