It's acceptable for implementation classes to be written to fit into existing code, but new classes must not instantiate managed properties or implement getters manually.

This is preferred:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()
}
```

This is acceptable:

```groovy
public interface NewThing {

# WebSockets { #websockets }

Bir [sanal ortam](../virtual-environments.md) oluşturduğunuzdan, onu aktive ettiğinizden ve `websockets`'i ("WebSocket" protokolünü kullanmayı kolaylaştıran bir Python kütüphanesi) kurduğunuzdan emin olun:

Wenn Sie einen entfernten Server (einen Cloud-Server, eine virtuelle Maschine, usw.) einrichten, können Sie am einfachsten `fastapi run` (welches Uvicorn verwendet) oder etwas Ähnliches manuell ausführen, genau wie bei der lokalen Entwicklung.

Und es wird funktionieren und **während der Entwicklung** nützlich sein.

### In a Remote Server { #in-a-remote-server }

When you set up a remote server (a cloud server, a virtual machine, etc.) the simplest thing you can do is use `fastapi run` (which uses Uvicorn) or something  similar, manually, the same way you do when developing locally.

And it will work and will be useful **during development**.

But if your connection to the server is lost, the **running process** will probably die.

        cos.flush();
        // Do NOT call getFile(), so done=false and close() will try to clean up
        // Delete the underlying file manually before close
        File file = cos.getFile(); // This sets done=true
        assertTrue(file.exists());
        file.delete();
        assertFalse(file.exists());
