Hi Hans, Thanks for your explanation.
Yup! I understand that any application can be written to read QoS settings from XML or other mechanism. I just thought that it will be a good feature to have if OpenSplice allows you to configure QoS via runtime using configuration file such as XML. Indeed perhaps a community project could be started to provide such capability. :-) Thanks again! - David On Fri, Aug 17, 2012 at 4:29 AM, Hans van't Hag <[email protected]>wrote: > Hi David, > > > > We don’t have proprietary API’s to create DDS_entities using external > (XML-)QoS descriptions.
