Bu örnekte `Union[PlaneItem, CarItem]` değerini `response_model` argümanına veriyoruz.

Bunu bir **type annotation** içine koymak yerine bir **argümana değer** olarak geçtiğimiz için, Python 3.10'da bile `Union` kullanmamız gerekiyor.

Eğer bu bir type annotation içinde olsaydı, dikey çizgiyi kullanabilirdik:

```Python
some_variable: PlaneItem | CarItem
```

        byte[] buffer = new byte[104]; // Exact size needed
        int offset = 0;

        setHeaderStart(response, 64);

        // Write structure
        SMBUtil.writeInt2(9, buffer, offset);
        SMBUtil.writeInt2(80 - 64, buffer, offset + 2);
        SMBUtil.writeInt4(24, buffer, offset + 4); // Exact notification size

        // Write notification
        int notifyOffset = 80;
