Does OpenSplice community edition support Topic and Group presentation QoS.I have found out that unless I put Instance presentation and with coherent access and ordered access attributes as false,there's error.In such a case,begin_coherent_access() does not show any difference compared to without begin_coherent_access().
As stated back in March 31th on the thread about OpenSplice Community features (and also in our reference-manuals), the non-default/optional TOPIC and GROUP PresentationQosPolicy settings are currently under development.
The TOPIC access-scope is planned for our next minor release update (5.2) as planned for the June timeframe.
The planning of the access-scope GROUP (which is part of the optional 'object-model-profile' of the DDS specification, see DDS rev. 1.2 chapter 2 "Compliance") will largely depend on customer-demand.
