<p>
Bonobo Activation also has a set of asynchronous activation interfaces so that you do not need to block
on activation calls. The CORBA level is pretty simple: the activation context has a set of
<code class="function">_async</code> calls: <code class="function">OAF_ACtivationContext_activate_async</code>
and <code class="function">OAF_ACtivationContext_activate_from_id_async</code>. Both of those calls
take an OAFActivationCallback CORBA object as parameter. This object, which is supposed to
be implemented by client applications (it is actually implemented in liboaf) will receive
CORBA calls when the activation is finished:
</p>
<pre class="programlisting">
module OAF {
interface ActivationCallback {
oneway void report_activation_failed (in string reason);
oneway void report_activation_succeeded (in ActivationResult result);
};
};
</pre>
<p>
</p>
<p>
Of course, libbonobo-activation provides comvenient wrappers for those CORBA functions. Those are named
<code class="function">bonobo_activation_activate_async</code> and
<code class="function">bonobo_activation_activate_from_id_async</code>.
