Eso significa que, los clientes que usan tu API no tienen que comprobar si el valor existe o no, pueden **asumir que el campo siempre estará allí**, pero solo que en algunos casos tendrá el valor por defecto de `None`.

La forma de describir esto en OpenAPI es marcar ese campo como **requerido**, porque siempre estará allí.

Debido a eso, el JSON Schema para un modelo puede ser diferente dependiendo de si se usa para **entrada o salida**:

      if (Helpers.equal(i.next().getKey(), newEntry.getKey())) {
        i.set(newEntry);
        return;
      }
    }

    throw new IllegalArgumentException(
        Platform.format("key %s not found in entries %s", newEntry.getKey(), expected));
  }

  /**
   * Wrapper for {@link Map#get(Object)} that forces the caller to pass in a key of the same type as

        assertEquals(8, bytesRead);
        assertTrue(fileInfo.toString().contains("endOfFile=" + value));
    }

    @Test
    @DisplayName("Test toString format")
    void testToString() {
        // Test default constructor
        String str1 = fileInfo.toString();
        assertNotNull(str1);
        assertTrue(str1.startsWith("EndOfFileInformation["));

/**
 * An object that converts literal text into a format safe for inclusion in a particular context
 * (such as an XML document). Typically (but not always), the inverse process of "unescaping" the
 * text is performed automatically by the relevant parser.

        PacDataInputStream pdis = createInputStream(data);
        SID sid = pdis.readId();
        // The readId method creates a SID with authority 5 and the RID value
        // Expected format: S-1-5-305419896
        String sidString = sid.toString();
        assertNotNull(sidString);
        assertEquals("S-1-5-305419896", sidString);
    }

    @Test

	case authTypeSignedV2, authTypeSigned, authTypeStreamingSigned:
		authtype = "REST-HEADER"
	case authTypePostPolicy:
		authtype = "POST"
	}

	args := map[string][]string{
		"CurrentTime":      {currTime.Format(time.RFC3339)},
		"EpochTime":        {strconv.FormatInt(currTime.Unix(), 10)},
		"SecureTransport":  {strconv.FormatBool(r.TLS != nil)},
		"SourceIp":         {handlers.GetSourceIPRaw(r)},

Dessa forma, contêineres consomem **poucos recursos**, uma quantidade comparável com rodar os processos diretamente (uma máquina virtual consumiria muito mais).

Esta definição de *schema* inclui as rotas da sua API, os parâmetros possíveis que elas usam, etc.

#### "*Schema*" de dados

O termo "*schema*" também pode se referir à forma de alguns dados, como um conteúdo JSON.

Nesse caso, significaria os atributos JSON e os tipos de dados que eles possuem, etc.
