| <div class="textblock"><p><b>Unsettled API</b> - A context for thread-safe execution of work. </p> |
| <p>Event-handler functions associated with a single <code><a class="el" href="classproton_1_1connection.html" title="A connection to a remote AMQP peer.">proton::connection</a></code> are called in sequence. The connection's <code><a class="el" href="classproton_1_1work__queue.html" title="Unsettled API - A context for thread-safe execution of work.">proton::work_queue</a></code> allows you to "inject" extra work from any thread and have it executed in the same sequence.</p> |
| <p>You may also create arbitrary <code><a class="el" href="classproton_1_1work__queue.html" title="Unsettled API - A context for thread-safe execution of work.">proton::work_queue</a></code> objects backed by a <a class="el" href="classproton_1_1container.html">container</a> that allow other objects to have their own serialised work queues that can have work injected safely from other threads. The <a class="el" href="classproton_1_1container.html">container</a> ensures that the work is correctly serialised.</p> |
| <p>The <code>proton::work</code> class represents the work to be queued and can be created from a function that takes no parameters and returns no value. </p> |
