同時我們希望能將那個固定內容參數化。

## 「callable」的實例 { #a-callable-instance }

在 Python 中有一種方式可以讓一個類別的實例變成「callable」。

不是類別本身（類別本來就可呼叫），而是該類別的實例。

要做到這點，我們宣告一個 `__call__` 方法：

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

在這個情境中，**FastAPI** 會用這個 `__call__` 來檢查額外的參數與子相依，並在之後呼叫它，把回傳值傳遞給你的「路徑操作函式」中的參數。

## 讓實例可參數化 { #parameterize-the-instance }

接著，我們可以用 `__init__` 來宣告這個實例的參數，用以「參數化」這個相依：

     */
    private boolean isKotlinFileFacadeClass(JApiCompatibility member) {
        return member instanceof JApiClass && ((JApiClass) member).getNewClass().isPresent() && KotlinMetadataQueries.INSTANCE.isKotlinFileFacadeClass(((JApiClass) member).getNewClass().get());
    }

### Descubrimiento de la aplicación { #application-discovery }

Dans ce cas, **FastAPI** vous fournit aussi les outils pour la construire.

///

    ba3[ba1.length - 1] = (byte) 43;
    ba4[ba1.length - 1] = (byte) 42;

    javaImpl = UnsignedBytes.lexicographicalComparatorJavaImpl();
    unsafeImpl = UnsignedBytes.LexicographicalComparatorHolder.UnsafeComparator.INSTANCE;
  }

  @Benchmark
  void longEqualJava(int reps) {
    for (int i = 0; i < reps; ++i) {
      if (javaImpl.compare(ba1, ba2) != 0) {
        throw new Error(); // deoptimization
      }
    }
  }

En realidad, `Query`, `Path` y otros que verás a continuación crean objetos de subclases de una clase común `Param`, que es a su vez una subclase de la clase `FieldInfo` de Pydantic.

Y `Field` de Pydantic también regresa una instance de `FieldInfo`.

`Body` también devuelve objetos de una subclase de `FieldInfo` directamente. Y hay otros que verás más adelante que son subclases de la clase `Body`.
