## Eine Instanz erstellen { #create-an-instance }

Wir könnten eine Instanz dieser Klasse erstellen mit:

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[18] *}

Und auf diese Weise können wir unsere Abhängigkeit „parametrisieren“, die jetzt `"bar"` enthält, als das Attribut `checker.fixed_content`.

## Die Instanz als Abhängigkeit verwenden { #use-the-instance-as-a-dependency }

   * object that equals a set member, but isn't the same instance. This behavior is similar to the
   * way {@code IdentityHashMap} handles key lookups.

  public static <E extends @Nullable Object> Set<E> newIdentityHashSet() {
    return Collections.newSetFromMap(Maps.newIdentityHashMap());
  }

但我们希望能够把这个固定内容参数化。

## “可调用”的实例 { #a-callable-instance }

在 Python 中，可以让某个类的实例变成“可调用对象”（callable）。

这里指的是类的实例（类本身已经是可调用的），而不是类本身。

为此，声明一个 `__call__` 方法：

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[12] *}

在这种情况下，**FastAPI** 会使用这个 `__call__` 来检查附加参数和子依赖，并且稍后会调用它，把返回值传递给你的*路径操作函数*中的参数。

## 参数化实例 { #parameterize-the-instance }

现在，我们可以用 `__init__` 声明实例的参数，用来“参数化”这个依赖项：

        assertEquals("250s", builder.timeoutSettings.clusterTimeout);
    }

    @Test
    public void testMethodChaining() {
        // Test that all methods return the builder instance for chaining
        String id = "chain-test";
        SuggestSettings settings = builder.setSettingsIndexName("CHAINED_INDEX")
                .addInitialSettings("chain.key1", "chainValue1")

        try {
            // Change default time zone temporarily
            TimeZone newTimeZone = TimeZone.getTimeZone("America/New_York");
            TimeZone.setDefault(newTimeZone);

            // Create new provider instance to pick up the new default
            FessUserTimeZoneProcessProvider newProvider = new FessUserTimeZoneProcessProvider();

            // Execute

#### MINIO_PUBLIC_IPS

This is comma separated list of IP addresses to which buckets created on this MinIO instance will resolve to. For example,
a bucket `bucket1` created on current MinIO instance will be accessible as `bucket1.domain.com`, and the DNS entry for
`bucket1.domain.com` will point to IP address set in `MINIO_PUBLIC_IPS`.
