Pero aquí está el punto clave.

El tema de seguridad e inyección de dependencias se escribe una vez.

Y puedes hacerlo tan complejo como desees. Y aún así, tenerlo escrito solo una vez, en un solo lugar. Con toda la flexibilidad.

Pero puedes tener miles de endpoints (*path operations*) usando el mismo sistema de seguridad.

        int len = invokeProtectedInt(obj, "writeParameterWordsWireFormat", buf, 0);

        // Expected size: 2 (sendBuffer) + 2 (mpxCount) + 2 (vcNumber) + 4 (sessionKey) + 2 (blob length) + 4 (reserved) + 4 (capabilities)
        int expected = 2 + 2 + 2 + 4 + 2 + 4 + 4;
        assertEquals(expected, len);

        int off = 0;
        assertEquals(65535, SMBUtil.readInt2(buf, off));
        off += 2;

Auf diese Weise wird deren Schema in der Benutzeroberfläche der API-Dokumentation angezeigt:

Daha önceden düşünüp en imkansız diyebileceğin durumlarda bile otomatik tamamlama alacaksın, örnek olarak `price` JSON body içerisinde (nested bir JSON body de olabilirdi.) direkt olarak istekten geliyor, bu durumda bile oto-tammalama sağlıyor.
