DDS15 — 'synchronous' and 'asynchronous' switched

  • Key: DDS15-34
  • Legacy Issue Number: 12465
  • Status: open  
  • Source: Anonymous
  • Summary:

    While reading the DDS specification, 'Data Distribution Service for Real-time Systems Version 1.2 OMG Available Specification formal/07-01-01', I found that the 'synchronous' and 'asynchronous' was switched as highlighted in red in the below paragraph in the spec.

    <section 'Overall Conceptual Model', page 9, penultimate paragraph>
    On the subscriber's side however, there are more choices: relevant information may arrive when the application is busy doing something else or when the application is just waiting for that information. Therefore, depending on the way the application is designed, asynchronous notifications or synchronous access may be more appropriate. Both interaction modes are allowed, a Listener is used to provide a callback for synchronous access and a WaitSet associated with one or several Condition objects provides asynchronous data access.
