<code class="sig">@Public @OnSpawn(Model) handler … { … }</code>
|
||||
<div class="desc"><p><code>@Public</code> stacks in front of a lifecycle hook to also emit a well-named event at the same moment the hook fires, so other modules (or mods) can react without touching the original code. It turns a private hook into a public seam: <code>@Public @OnSpawn(Model)</code> emits <code>model_<Model>_spawn</code>, <code>@OnDespawn</code> emits <code>model_<Model>_despawn</code>, the property hooks emit <code>prop_<Property>_attach</code>/<code>_detach</code>/<code>_enable</code>/<code>_disable</code>, and <code>@OnStart</code>/<code>@OnQuit</code> emit <code>program_start</code>/<code>program_quit</code>. This is the same lowering the event system uses, so anyone can <code>@On</code> the generated event to extend behavior at that lifecycle point. Add it when a hook marks an extension point you want to keep open across a modular codebase.</p></div>
