A class that can invoke its own methods in a delayed way. 
<p>
Via the method <a class="el" href="class_context_provider_1_1_queued_invoker.html#6b26e01ea4e92ca556e9d7ddedbe8881" title="Sets the method method to be invoked when the event loop of this object runs next...">QueuedInvoker::queueOnce</a>, the given method is set to be invoked when the event loop of the object is entered. Each method is queued at most once. <a class="el" href="class_context_provider_1_1_queued_invoker.html" title="A class that can invoke its own methods in a delayed way.">QueuedInvoker</a> sends a signal to itself, and when the signal is processed, the method is invoked.<p>
