Interceptors
============

Interceptors are a powerful mechanism that can monitor, rewrite, and retry calls. Here's a simple interceptor that logs the outgoing request and the incoming response.

```java
class LoggingInterceptor implements Interceptor {
  @Override public Response intercept(Interceptor.Chain chain) throws IOException {
    Request request = chain.request();

    long t1 = System.nanoTime();

Aquí hay algunos ejemplos de cuándo eso podría tener sentido:

#### Una Aplicación Simple { #a-simple-app }

Podrías querer un gestor de procesos en el contenedor si tu aplicación es **lo suficientemente simple** que pueda ejecutarse en un **servidor único**, no un cluster.

#### Docker Compose { #docker-compose }

        // Scenario: DFS is disabled.
        when(mockConfig.isDfsDisabled()).thenReturn(true);
        DfsReferralDataInternal mockReferral = mock(DfsReferralDataInternal.class);
        // Should not throw any exception and simply return.
        assertDoesNotThrow(() -> dfsImpl.cache(mockContext, "\\\\server\\share\\path", mockReferral));
    }

    @Test
    void testCache_InvalidPath() {

### Bir `Enum` Sınıfı Oluşturalım

`Enum` sınıfını projemize dahil edip `str` ile `Enum` sınıflarını miras alan bir alt sınıf yaratalım.

`str` sınıfı miras alındığından dolayı, API dokümanı, değerlerin `string` tipinde olması gerektiğini anlayabilecek ve doğru bir şekilde işlenecektir.

## Ejemplo { #example }

Para un ejemplo simple, consideremos una estructura de archivos similar a la descrita en [Aplicaciones Más Grandes](../tutorial/bigger-applications.md){.internal-link target=_blank} y [Testing](../tutorial/testing.md){.internal-link target=_blank}:

```
.
├── app

Imaginemos que cargar el modelo puede **tomar bastante tiempo**, porque tiene que leer muchos **datos del disco**. Entonces no quieres hacerlo para cada request.

    return future instanceof FluentFuture
        ? (FluentFuture<V>) future
        : new ForwardingFluentFuture<V>(future);
  }

  /**
   * Simply returns its argument.
   *
   * @deprecated no need to use this
   * @since 28.0

  @InlineMe(
      replacement = "checkNotNull(future)",

### Response HTTP { #http-response }

La aplicación procesaría el request y enviaría un **response HTTP simple (sin encriptar)** al TLS Termination Proxy.
