Property<String> getSomeProperty()
}
class Example {
    @Nested
    NestedType getNestedProperty()
}
```
Otherwise, if the nested type requires an implementation class, you'll need to manage the lifecycle of it:
```
interface NestedType {
    Property<String> getSomeProperty()
    void notManaged()
}
abstract class DefaultNestedType implements NestedType {
    ...
}

class Example {
    private final NestedType nested

        java.lang.reflect.Field field = TestBean.class.getDeclaredField("directField");

        // First access
        helper.setProperty(bean1, "directField", String.class, config);
        boolean accessibilityAfterFirst = field.canAccess(bean1);

        // Second access with different bean
        config.setValue("value2");
        helper.setProperty(bean2, "directField", String.class, config);

    Call call = client.newCall(request);

    assertEquals(5, call.tag(Integer.class));
    assertEquals("hello", call.tag(String.class));
    assertEquals(null, call.tag(Boolean.class));
    assertEquals(null, call.tag(Object.class));
  }

  @Test
  public void tagsCanBeComputed() {
    Request request = new Request.Builder()
      .url(HttpUrl.get("https://square.com/"))
      .build();
    Call call = client.newCall(request);

This is a toy example to demonstrate how it works, if you need Gzip support, you can use the provided [`GzipMiddleware`](../advanced/middleware.md#gzipmiddleware){.internal-link target=_blank}.
