UML25 — Question About Arrows In Communication Diagramms

Open Closed All
  • Key: UML25-664
  • Legacy Issue Number: 17398
  • Status: closed  
  • Source: Anonymous
  • Summary:

    wonder about the arrows used in communication diagramms (superstructure
    spec, Page 524).
    Do they indicate the type of message - as it is with sequence diagramms
    (sync, async) - or do they indicate the direction of message only.
    I didn't find a statement in the superstructure spec and several UML related
    books offered different oppinions.

  • Disposition Summary:

    Communication diagram can have replies shown, because it can represent any message. There is only the solid arrow
    style in communication diagrams.
