<p>Triggers in the <a class="reference external" href="process_group.html">process group</a> interface are used to asynchronously
|
|
receive and process messages destined for distributed data
|
|
structures. The trigger interface is relatively versatile, permitting
|
|
one to attach any function object to handle requests. The
|
|
<tt class="docutils literal"><span class="pre">simple_trigger</span></tt> function simplifies a common case for triggers:
|
|
attaching a trigger that invokes a specific member function of the
|
|
distributed data structure.</p>

<p>The <tt class="docutils literal"><span class="pre">simple_trigger</span></tt> function registers a trigger that invokes the
|
|
given member function (<tt class="docutils literal"><span class="pre">pmf</span></tt>) on the object <tt class="docutils literal"><span class="pre">self</span></tt> whenever a
|
|
message is received. If the member function has a return value, then
|
|
the trigger has a reply, and can only be used via out-of-band sends
|
|
that expect a reply. Otherwise, the member function returns <tt class="docutils literal"><span class="pre">void</span></tt>,
|
|
and the function is registered as a normal trigger.</p>
