DDS15 — Allow for more optimized list returned by get_datareaders()

  • Key: DDS15-22
  • Legacy Issue Number: 17364
  • Status: open

  • Summary:

    Found by: Fernando Crespo

    OMG DDS spec (section states that the sequence returned by
    get_datareaders() will contain list containing each DataReader one or more times.
    For example, if multiple consecutive samples in a group belong to the same DataReader
    the DataReader is repeated in the list returned by get_datareaders().
    Having to process each element, even when they belong to the same DataReader is
    less performant.

    Proposed Resolution:
    Modify the specification to return one DataReader element, instead of a list where
    a DataReader is repeated multiple times, when multiple subsequent samples belong to
    the same DataReader. This allows for more optimized processing where the user calls
    read/take until the return code is NO_DATA.
