<p>Emitted when the threaded job is complete.</p>
<p>The default implementation simply emits the <a class="link" href="UDisksJob.html#UDisksJob-completed" title="The “completed” signal"><span class="type">“completed”</span></a>
signal with <em class="parameter"><code>success</code></em>
 set to <code class="literal">TRUE</code> if, and only if, <em class="parameter"><code>error</code></em>
 is
<code class="literal">NULL</code>. Otherwise, <em class="parameter"><code>message</code></em>
 on that signal is set to a string
describing <em class="parameter"><code>error</code></em>
. You can avoid the default implementation by
returning <code class="literal">TRUE</code> from your signal handler.</p>
<p>This signal is emitted in the</p>
thread-default main loop<p>of the thread that <em class="parameter"><code>job</code></em>
 was created in.</p>
