Sehen wir uns das alles anhand eines Beispiels an.

Stellen Sie sich vor, Sie entwickeln eine Anwendung, mit der Sie Rechnungen erstellen können.

Diese Rechnungen haben eine `id`, einen optionalen `title`, einen `customer` (Kunde) und ein `total` (Gesamtsumme).

Der Benutzer Ihrer API (ein externer Entwickler) erstellt mit einem POST-Request eine Rechnung in Ihrer API.

Dann wird Ihre API (stellen wir uns vor):

        v.add(new DERTaggedObject(true, 2, new DERBitString(new byte[] { 0x01 })));

        // Create a custom APPLICATION tagged object that throws IOException when encoding
        // We need to create a proper ASN1TaggedObject with APPLICATION tag class
        // Create a custom base object that throws IOException
        ASN1Encodable badBase = new ASN1Encodable() {
            @Override

                    }
                },
                "x-aperture-labs-portal": "blue"
            }
        }
    }
}
```

### Esquema de *path operation* personalizada de OpenAPI { #custom-openapi-path-operation-schema }

El diccionario en `openapi_extra` se combinará profundamente con el esquema de OpenAPI generado automáticamente para la *path operation*.

                    }
                },
                "x-aperture-labs-portal": "blue"
            }
        }
    }
}
```

### Esquema de *operação de rota* do OpenAPI personalizado { #custom-openapi-path-operation-schema }

O dicionário em `openapi_extra` vai ter todos os seus níveis mesclados dentro do esquema OpenAPI gerado automaticamente para a *operação de rota*.

// constructor initializes.
func DomainNames(domainNames []string) EtcdOption {
	return func(args *CoreDNS) {
		args.domainNames = domainNames
	}
}

// DomainIPs set a list of custom domain IPs, note this will
// fail if set to empty when constructor initializes.
func DomainIPs(domainIPs set.StringSet) EtcdOption {
	return func(args *CoreDNS) {
		args.domainIPs = domainIPs
	}
}

 * <p>This service allows implementations to:</p>
 * <ul>
 *   <li>Pool identical objects to reduce memory footprint</li>
 *   <li>Intern objects for faster equality comparisons</li>
 *   <li>Apply custom optimization strategies</li>
 *   <li>Transform or modify objects during building</li>
 * </ul>

 * <p>Implementations are discovered via the Java ServiceLoader mechanism and should

   *       visible static factory method whose return type is {@code C} or {@code C}'s subtype.
   * </ul>
   *
   * <p>In all cases, if {@code C} needs custom logic for testing serialization, you can add an
   * explicit {@code testSerializable()} test in the corresponding {@code CTest} class, and {@code
   * C} will be excluded from automated serialization test performed by this method.

            data["client_secret"] = form_data.client_secret
        return data

    Note that for OAuth2 the scope `items:read` is a single scope in an opaque string.
    You could have custom internal logic to separate it by colon characters (`:`) or
    similar, and get the two parts `items` and `read`. Many applications do that to
    group and organize permissions, you could do it as well in your application, just

        assertNotNull(result);
        assertNotNull(result.getContent());
        assertTrue(result.getContent().contains("Test content"));
    }

    /**
     * Test successful text extraction with custom encoding.
     */
    public void test_getText_withCustomEncoding() {
        textExtractor.setEncoding("UTF-8");
        final String testContent = "テスト内容";
