Dann können Sie diese neue Klasse mit `response_class=PNGStreamingResponse` in Ihrer Pfadoperation-Funktion verwenden:

### Eine Datei simulieren { #simulate-a-file }

In diesem Beispiel simulieren wir eine Datei mit `io.BytesIO`, einem dateiähnlichen Objekt, das nur im Speicher lebt, uns aber dieselbe Schnittstelle nutzen lässt.

### Déclarer des *chemins d'accès* avec `APIRouter` { #path-operations-with-apirouter }

Puis vous l'utilisez pour déclarer vos *chemins d'accès*.

Utilisez-le de la même manière que vous utiliseriez la classe `FastAPI` :

    setImplementation(Appendable.class, StringBuilder.class);
    setImplementation(BlockingQueue.class, LinkedBlockingDeque.class);
    setImplementation(BlockingDeque.class, LinkedBlockingDeque.class);
    setImplementation(ConcurrentMap.class, ConcurrentHashMap.class);
    setImplementation(ConcurrentNavigableMap.class, ConcurrentSkipListMap.class);
    setImplementation(CountDownLatch.class, Dummies.DummyCountDownLatch.class);

            // When
            Method writeParams = SmbComNtCancel.class.getDeclaredMethod("writeParameterWordsWireFormat", byte[].class, int.class);
            writeParams.setAccessible(true);
            writeParams.invoke(cancel, dst, 0);

            Method writeBytes = SmbComNtCancel.class.getDeclaredMethod("writeBytesWireFormat", byte[].class, int.class);
            writeBytes.setAccessible(true);

            Object wrapper = newPrivateInner("ResourceNameFilterWrapper", new Class<?>[] { SmbFilenameFilter.class }, delegate);

            SmbResource notAFileParent = mock(SmbResource.class);

            // Act
            boolean result =
                    (boolean) invokePrivate(wrapper, "accept", new Class<?>[] { SmbResource.class, String.class }, notAFileParent, "name");

  public void testGenericInterface() {
    // test the 1st generic interface on the class
    Type fType = Supplier.class.getTypeParameters()[0];
    assertEquals(
        Integer.class, TypeToken.of(IntegerStringFunction.class).resolveType(fType).getRawType());

    // test the 2nd generic interface on the class
    Type predicateParameterType = Predicate.class.getTypeParameters()[0];
    assertEquals(

  public void testGenericInterface() {
    // test the 1st generic interface on the class
    Type fType = Supplier.class.getTypeParameters()[0];
    assertEquals(
        Integer.class, TypeToken.of(IntegerStringFunction.class).resolveType(fType).getRawType());

    // test the 2nd generic interface on the class
    Type predicateParameterType = Predicate.class.getTypeParameters()[0];
    assertEquals(

        .containsExactly(Foo.class);
