Vous pouvez définir une logique (du code) qui doit être exécutée avant que l'application ne **démarre**. Cela signifie que ce code sera exécuté **une seule fois**, **avant** que l'application ne **commence à recevoir des requêtes**.

If the effect of an atomic operation <i>A</i> is observed by atomic operation <i>B</i>,
then <i>A</i> is synchronized before <i>B</i>.
All the atomic operations executed in a program behave as though executed
in some sequentially consistent order.
</p>

<p>
The preceding definition has the same semantics as C++’s sequentially consistent atomics
and Java’s <code>volatile</code> variables.
