DDSXTY12 — lookup_topicdescription semantics make it unusable

  • Key: DDSXTY12-32
  • Legacy Issue Number: 18309
  • Status: closed  
  • Source: ZettaScale Technology ( Erik Hendriks)
  • Summary:

    Section specifies that lookup_topicdescription returns 1 matching representation. On multiple matches, an arbitrary representation is returned.

    This is not helpful in any way for an application trying to access a certain representation. Either its signature should be changed to return a sequence of topic representations, or it should cyclically go over each representation and return 1 at a time, so that subsequent invocations may return different representations.
