[Ace-users] Re: [ciao-users] Invoking push_event on a component

[Sowayan, Abdullah (N-DUA)]

Santos,

We at Lockheed Martin do not provide support for CIAO. Please forward
all your questions regarding CIAO to the CIAO user's list. Quite
frankly, you might even get a better response by someone who knows CIAO
and Light Weight CCM more than us (for instance, the CIAO developers at
Vanderbilt or RemedyIT).

You're referring to the Hello example in $CIAO_ROOT/examples/Hello. When
you run the idl file through the CIDL compiler, it will generate an
executor IDL (RecieverE.idl). That IDL will show you the inheritance
hierarchy. Also Doug's presentation on Light Weight CCM talks about the
rules of such mapping in detail, I highly recommend you look at that
presentation.

Hmmm, it really depends on what you're trying to do. If you knew
everything about your components and their deployment statically, then
I'd recommend you use the Deployment and Configuration Engine of CIAO
(called DAnCE) to do all the connections between Facets and Receptacles,
Event Sources and Event Sinks for you. If that's not the case, then if
you have an object reference to the component you can query it for such
things (Facet, Receptacle, etc) and manage establishing the connections
yourself.

Thanks,
Abdul
