## Einfache Verwendung

Näher betrachtet, werden *Pfadoperation-Funktionen* deklariert, um verwendet zu werden, wann immer ein *Pfad* und eine *Operation* übereinstimmen, und dann kümmert sich **FastAPI** darum, die Funktion mit den richtigen Parametern aufzurufen, die Daten aus der Anfrage extrahierend.

```Python
some_variable: PlaneItem | CarItem
```

하지만 이를 `response_model=PlaneItem | CarItem`과 같이 할당하면 에러가 발생합니다. 이는 Python이 이를 타입 어노테이션으로 해석하지 않고, `PlaneItem`과 `CarItem` 사이의 **잘못된 연산(invalid operation)**을 시도하기 때문입니다

## 모델 리스트

마찬가지로, 객체 리스트 형태의 응답을 선언할 수도 있습니다.

이를 위해 표준 Python의 `typing.List`를 사용하세요(또는 Python 3.9 이상에서는 단순히 `list`를 사용할 수 있습니다):

        // Insert will trigger MappingUpdater which will be closed automatically
        charMappingFile.insert(newItem);

        // Verify the operation completed successfully despite any internal errors
        PagingList<CharMappingItem> result = charMappingFile.selectList(0, 10);
        assertEquals(2, result.size());
    }

        System.arraycopy(buffer, bodyOffset + 8, actualPath, 0, pathBytes.length);
        assertArrayEquals(pathBytes, actualPath);
    }

    @Test
    @DisplayName("Should handle chain operation correctly")
    void testChain() {
        // Given
        ServerMessageBlock2 nextMessage = mock(ServerMessageBlock2.class);

        // When
        boolean result = request.chain(nextMessage);

  interface Strategy extends java.io.Serializable {

    /**
     * Sets {@code numHashFunctions} bits of the given bit array, by hashing a user element.
     *
     * <p>Returns whether any bits changed as a result of this operation.
     */
    <T extends @Nullable Object> boolean put(
        @ParametricNullness T object,
        Funnel<? super T> funnel,
        int numHashFunctions,
        LockFreeBitArray bits);
