DDSXTY12 — Extended parameters should be aligned the same as non-extended ones

  • Key: DDSXTY12-39
  • Legacy Issue Number: 17297
  • Status: closed  
  • Source: DECA ( Rick Warren)
  • Summary:

    Found by: Fernando Crespo, RTI (
    Severity: Support Text

    The section on the parameterized CDR Data Representation (DDS-XTypes contains a reference to the DDS-RTPS specification for the definition of the parameter list data structure. However, it does not specifically refer to the instructions in DDS-RTPS on how to handle alignment within such a structure. This omission may confuse some implementers, especially with respect to extended parameters, which should follow the same alignment rules as RTPS-traditional "short" parameters.

    Proposed Resolution:
    Add the following paragraph to the end of section, "Interpretation of Parameter ID Values":

    "The alignment rules for extended parameters shall be the same as
    those for non-extended parameters, which are defined in [RTPS]
