# Response-Header { #response-headers }

## Einen `Response`-Parameter verwenden { #use-a-response-parameter }

Sie können einen Parameter vom Typ `Response` in Ihrer *Pfadoperation-Funktion* deklarieren (wie Sie es auch für Cookies tun können).

Und dann können Sie Header in diesem *vorübergehenden* <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr>-Objekt festlegen.

        default:
            return "Unknown error: 0x" + Integer.toHexString(returnCode);
        }
    }

    /**
     * Encodes the witness RPC message parameters to NDR format.
     * Subclasses must implement this method to encode their specific parameters.
     *
     * @param buf the NDR buffer to encode into
     * @throws NdrException if encoding fails
     */

Se você quiser:

* declarar o parâmetro de consulta `q` sem um `Query` nem qualquer valor padrão
* declarar o parâmetro de path `item_id` usando `Path`
* tê-los em uma ordem diferente
* não usar `Annotated`

...o Python tem uma pequena sintaxe especial para isso.

Passe `*`, como o primeiro parâmetro da função.

    private final Map<String, Parameter> missingParameters;

    ValidatingConfigurationListener(Object mojo, MojoDescriptor mojoDescriptor, ConfigurationListener delegate) {
        this.mojo = mojo;
        this.delegate = delegate;
        this.missingParameters = new HashMap<>();

        if (mojoDescriptor.getParameters() != null) {
            for (Parameter param : mojoDescriptor.getParameters()) {

    /**
     * Constructs a new HostIntervalController with default parameters.
     */
    public HostIntervalController() {
        this.lastTimes = CacheBuilder.newBuilder().expireAfterAccess(DEFAULT_CACHE_EXPIRE_HOURS, TimeUnit.HOURS).build();
    }

    /**
     * Constructs a new HostIntervalController with the specified parameters.
     *
     * @param params the parameters to configure the interval controller
     */

As an example, let's take this function:

{* ../../docs_src/python_types/tutorial009c_py39.py hl[1,4] *}

The parameter `name` is defined as `Optional[str]`, but it is **not optional**, you cannot call the function without the parameter:

```Python
say_hi()  # Oh, no, this throws an error! 😱
```

The `name` parameter is **still required** (not *optional*) because it doesn't have a default value. Still, `name` accepts `None` as the value:

        return now + days * Constants.ONE_DAY_IN_MILLIS;
    }

     */
    public Map<String, String> getInfoMap(final String sessionId) {
