## Modelos Anidados { #nested-models }

Cada atributo de un modelo Pydantic tiene un tipo.

Pero ese tipo puede ser en sí mismo otro modelo Pydantic.

Así que, puedes declarar "objetos" JSON anidados profundamente con nombres de atributos específicos, tipos y validaciones.

Todo eso, de manera arbitraria.

### Definir un submodelo { #define-a-submodel }

Por ejemplo, podemos definir un modelo `Image`:

        assertFalse(isPositive.apply(null));
    }

    @Test
    public void test_apply_object() {
        BooleanFunction<Object> isNotNull = obj -> obj != null;

        assertTrue(isNotNull.apply("test"));
        assertTrue(isNotNull.apply(123));
        assertTrue(isNotNull.apply(new Object()));
        assertFalse(isNotNull.apply(null));
    }

    @Test
    public void test_apply_boolean() {

  @Override
  public SampleElements<Integer> samples() {
    return new Ints();
  }

  @Override
  public Set<Integer> create(Object... elements) {
    Integer[] array = new Integer[elements.length];
    int i = 0;
    for (Object e : elements) {
      array[i++] = (Integer) e;
    }
    return create(array);
  }

  protected abstract Set<Integer> create(Integer[] elements);

@NullMarked
public class AbstractListMultimapTester<K extends @Nullable Object, V extends @Nullable Object>
    extends AbstractMultimapTester<K, V, ListMultimap<K, V>> {

  @Override
  protected void assertGet(K key, V... values) {
    assertGet(key, asList(values));
  }

  @Override

  @Override
  public SampleElements<AnEnum> samples() {
    return new Enums();
  }

  @Override
  public Multiset<AnEnum> create(Object... elements) {
    AnEnum[] array = new AnEnum[elements.length];
    int i = 0;
    for (Object e : elements) {
      array[i++] = (AnEnum) e;
    }
    return create(array);
  }

  protected abstract Multiset<AnEnum> create(AnEnum[] elements);
