DDSXTY14 — Data Representation for RTPS's Serialized Key

  • Key: DDSXTY14-38
  • Status: open   Implementation work Blocked
  • Source: Object Computing, Inc. - OCI ( Adam Mitz)
  • Summary:

    RTPS 2.3 section 9.4.5.3.1
    "D=0 and K=1 means that the serializedPayload SubmessageElement contains the serialized Key."

    XTypes section 7.4 "Data Representation" should define the rules for encoding an object of a type defined by the 7.2 "Type System" to a Key-only serialization.

    Using what's currently in the spec, there are two potential interpretations:

    a. follow all the encoding rules as for a full object (adding DHeader, EMHeader, etc.) but any part of that object that's not a key gets skipped, using 7.2.2.4.7 to determine what's a key

    b. use the rules in 7.6.8 (which are explicitly only for a KeyHash) to get a KeyHolder object and then encode that
