Subject Re: Mixed oneway and normal/synchronous UNO interface calls
Date Tue, 11 Sep 2012 08:20:52 GMT
We have done tests here and it works as described: when a synchronous call follows previous
oneway calls, it waits until the oneeways are finished. The sequence is ordered for the caller

We used OpenOffice URE and SDK sources Version 2.3.0 (OO680_m5).

As far as I remember our company chose UNO as backbone of the newer, component-based parts
of the software because of

- the minimal overhead when calling into a service when it is in the same process (a virtual
method call)
- the ability to cope with a large number of interfaces and services, also regarding compile
- ease of debugging and the possibility to debug across component borders

They use oneway calls a lot: in this way they can reduce the IPC traffic between clients and
a server application. At the end of a task they issue a synchronous call, collecting the results
form so-called "remote variables".

Thanks, Karsten
