Interface for entities having fields.

This interface builds upon the general interfaces provided by the typed data API, while extending them with entity-specific additions. I.e., fieldable entities implement the ComplexDataInterface among others, thus it is complex data containing fields as its data properties. The contained fields have to implement \Drupal\Core\Field\FieldItemListInterface, which builds upon typed data interfaces as well.

When implementing this interface which extends Traversable, make sure to list IteratorAggregate or Iterator before this interface in the implements clause.

    /**
     * Provides base field definitions for an entity type.
     *
     * Implementations typically use the class
     * \Drupal\Core\Field\BaseFieldDefinition for creating the field definitions;
     * for example a 'name' field could be defined as the following:
     * @code
     * $fields['name'] = BaseFieldDefinition::create('string')
     *   ->setLabel(t('Name'));
     * @endcode
     *
     * By definition, base fields are fields that exist for every bundle. To
     * provide definitions for fields that should only exist on some bundles, use
     * \Drupal\Core\Entity\FieldableEntityInterface::bundleFieldDefinitions().
     *
     * The definitions returned by this function can be overridden for all
     * bundles by hook_entity_base_field_info_alter() or overridden on a
     * per-bundle basis via 'base_field_override' configuration entities.
     *
     * @param \Drupal\Core\Entity\EntityTypeInterface $entity_type
     *   The entity type definition. Useful when a single class is used for multiple,
     *   possibly dynamic entity types.
     *
     * @return \Drupal\Core\Field\FieldDefinitionInterface[]
     *   An array of base field definitions for the entity type, keyed by field
     *   name.

     * are not defined in $base_field_definitions, and therefore might not exist
     * on some bundles) as well as bundle-specific overrides of base fields
     * (fields that are defined in $base_field_definitions, and therefore exist
     * for all bundles). However, bundle-specific base field overrides can also
     * be provided by 'base_field_override' configuration entities, and that is
     * the recommended approach except in cases where an entity type needs to
     * provide a bundle-specific base field override that is decoupled from
     * configuration. Note that for most entity types, the bundles themselves are
     * derived from configuration (e.g., 'node' bundles are managed via
     * 'node_type' configuration entities), so decoupling bundle-specific base
     * field overrides from configuration only makes sense for entity types that
     * also decouple their bundles from configuration. In cases where both this
     * function returns a bundle-specific override of a base field and a
