![Interceptors Diagram](../assets/images/******@****.***)

### Application Interceptors

Interceptors are registered as either _application_ or _network_ interceptors. We'll use the `LoggingInterceptor` defined above to show the difference.

Register an _application_ interceptor by calling `addInterceptor()` on `OkHttpClient.Builder`:

```java
OkHttpClient client = new OkHttpClient.Builder()

   *
   * @throws IllegalStateException if this service's state isn't {@linkplain State#FAILED FAILED}.
   * @since 14.0
   */
  Throwable failureCause();

  /**
   * Registers a {@link Listener} to be {@linkplain Executor#execute executed} on the given
   * executor. The listener will have the corresponding transition method called whenever the

      eventsReceived.add(event);
    }
  }

  public void testEventOrderingIsPredictable() {
    EventProcessor processor = new EventProcessor();
    bus.register(processor);

    EventRecorder recorder = new EventRecorder();
    bus.register(recorder);

    bus.post(FIRST);

    assertEquals(
        "EventRecorder expected events in order",
        Lists.<Object>newArrayList(FIRST, SECOND),

            String msg = "Cannot register null or empty aggregation: name=" + name + " value=" + value;
            throw new InvalidQueryRegisteredException(msg);
        }
    }

    protected void checkEsInvalidAggregationCollection(String name, Collection<?> values) {
        if (values == null || values.isEmpty()) {

  configurations {
    val friendsApi = register("friendsApi") {
      isCanBeResolved = true
      isCanBeConsumed = false
      isTransitive = true
    }
    val friendsImplementation = register("friendsImplementation") {
      isCanBeResolved = true
      isCanBeConsumed = false
      isTransitive = false
    }
