  /**
   * Adds field widgets to an entity form.
   *
   * The form elements for the entity's fields are added by reference as direct
   * children in the $form parameter. This parameter can be a full form
   * structure (most common case for entity edit forms), or a sub-element of a
   * larger form.
   *
   * By default, submitted field values appear at the top-level of
   * $form_state->getValues(). A different location within
   * $form_state->getValues() can be specified by setting the '#parents'
   * property on the incoming $form parameter. Because of name clashes, two
   * instances of the same field cannot appear within the same $form element, or
   * within the same '#parents' space.
   *
   * Sample resulting structure in $form:
   * @code
   *   '#parents' => The location of field values in $form_state->getValues(),
   *   '#entity_type' => The name of the entity type,
   *   '#bundle' => The name of the bundle,
   *   // One sub-array per field appearing in the entity, keyed by field name.
   *   // The structure of the array differs slightly depending on whether the
   *   // widget is 'single-value' (provides the input for one field value,
   *   // most common case), and will therefore be repeated as many times as
   *   // needed, or 'multiple-values' (one single widget allows the input of
   *   // several values; e.g., checkboxes, select box, etc.).
   *   'field_foo' => array(
   *     '#access' => TRUE if the current user has 'edit' grants for the field,
   *       FALSE if not.
   *     'widget' => array(
   *       '#field_name' => The name of the field,
   *       '#title' => The label of the field,
   *       '#description' => The description text for the field,
   *       '#required' => Whether or not the field is required,
   *       '#field_parents' => The 'parents' space for the field in the form,
   *          equal to the #parents property of the $form parameter received by
   *          this method,
   *
   *       // For 'multiple-value' widgets, the remaining elements in the
   *       // sub-array depend on the widget.
   *
   *       // For 'single-value' widgets:
   *       '#theme' => 'field_multiple_value_form',
   *       '#cardinality' => The field cardinality,
   *       '#cardinality_multiple' => TRUE if the field can contain multiple
   *         items, FALSE otherwise.
   *       // One sub-array per copy of the widget, keyed by delta.
   *       0 => array(
   *         '#title' => The title to be displayed by the widget,
   *         '#description' => The description text for the field,
   *         '#required' => Whether the widget should be marked required,
   *         '#delta' => 0,
   *         '#weight' => 0,
   *         '#field_parents' => Same as above,
   *         // The remaining elements in the sub-array depend on the widget.
   *         ...
   *       ),
   *       1 => array(
   *         ...
   *       ),
   *       ...
   *     ),
   *     ...
   *   ),
   * )
   * @endcode
   *
   * Additionally, some processing data is placed in $form_state, and can be
   * accessed by \Drupal\Core\Field\WidgetBaseInterface::getWidgetState() and
   * \Drupal\Core\Field\WidgetBaseInterface::setWidgetState().
   *
   * @param \Drupal\Core\Entity\FieldableEntityInterface $entity
   *   The entity.
   * @param array $form
   *   The form structure to fill in. This can be a full form structure, or a
   *   sub-element of a larger form. The #parents property can be set to
   *   control the location of submitted field values within
   *   $form_state->getValues(). If not specified, $form['#parents'] is set to
   *   an empty array, which results in field values located at the top-level of
   *   $form_state->getValues().
   * @param \Drupal\Core\Form\FormStateInterface $form_state
   *   The form state.

  /**
   * Validates submitted widget values and sets the corresponding form errors.
   *
   * This method invokes entity validation and takes care of flagging them on
   * the form. This is particularly useful when all elements on the form are
   * managed by the form display.
   *
   * As an alternative, entity validation can be invoked separately such that
   * some violations can be flagged manually. In that case
   * \Drupal\Core\Entity\Display\EntityFormDisplayInterface::flagViolations()
   * must be used for flagging violations related to the form display.
   *
   * Note that there are two levels of validation for fields in forms: widget
   * validation and field validation:
   * - Widget validation steps are specific to a given widget's own form
   *   structure and UI metaphors. They are executed during normal form
   *   validation, usually through Form API's #element_validate property.
   *   Errors reported at this level are typically those that prevent the
   *   extraction of proper field values from the submitted form input.
   * - If no form / widget errors were reported for the field, field validation
   *   steps are performed according to the "constraints" specified by the
   *   field definition as part of the entity validation. That validation is
   *   independent of the specific widget being used in a given form, and is
   *   also performed on REST entity submissions.
   *
   * @param \Drupal\Core\Entity\FieldableEntityInterface $entity
   *   The entity.
   * @param array $form
   *   The form structure where field elements are attached to. This might be a
   *   full form structure, or a sub-element of a larger form.
   * @param \Drupal\Core\Form\FormStateInterface $form_state
   *   The form state.

   * related to fields of the form display must be processed before this method

   *
   * The method flags constraint violations related to fields shown on the
   * form as form errors on the correct form elements. Possibly pre-existing
