* This involves the same hooks and operations as regular entity loading.
*
+ * @section entities_revisions_translations Entities, revisions and translations
+ *
+ * A translation is not a revision and a revision is not necessarily a
+ * translation. Revisions and translations are the two axes on the "spreadsheet"
+ * of an entity. If you use the built-in UI and have revisions enabled, then a
+ * new translation change would create a new revision (with a copy of all data
+ * for other languages in that revision). If an entity does not use revisions or
+ * the entity is being modified via the API, then multiple translations can be
+ * modified in a single revision. Conceptually, the revisions are columns on the
+ * spreadsheet and translations are rows.
+ *
* @section save Save operations
* To update an existing entity, you will need to load it, change properties,
* and then save; as described above, when creating a new entity, you will also
* either \Drupal\Core\Config\Entity\ConfigEntityBase or
* \Drupal\Core\Entity\ContentEntityBase, with annotation for
* \@ConfigEntityType or \@ContentEntityType in its documentation block.
- * - The 'id' annotation gives the entity type ID, and the 'label' annotation
- * gives the human-readable name of the entity type. If you are defining a
- * content entity type that uses bundles, the 'bundle_label' annotation gives
- * the human-readable name to use for a bundle of this entity type (for
- * example, "Content type" for the Node entity).
+ * If you are defining a content entity type, it is recommended to extend the
+ * \Drupal\Core\Entity\EditorialContentEntityBase base class in order to get
+ * out-of-the-box support for Entity API's revisioning and publishing
+ * features, which will allow your entity type to be used with Drupal's
+ * editorial workflow provided by the Content Moderation module.
+ * - In the annotation, the 'id' property gives the entity type ID, and the
+ * 'label' property gives the human-readable name of the entity type. If you
+ * are defining a content entity type that uses bundles, the 'bundle_label'
+ * property gives the human-readable name to use for a bundle of this entity
+ * type (for example, "Content type" for the Node entity).
* - The annotation will refer to several handler classes, which you will also
* need to define:
* - list_builder: Define a class that extends
* \Drupal\Core\Entity\EntityViewBuilderInterface (usually extending
* \Drupal\Core\Entity\EntityViewBuilder), to display a single entity.
* - translation: For translatable content entities (if the 'translatable'
- * annotation has value TRUE), define a class that extends
+ * annotation property has value TRUE), define a class that extends
* \Drupal\content_translation\ContentTranslationHandler, to translate
* the content. Configuration translation is handled automatically by the
* Configuration Translation module, without the need of a handler class.
* - access: If your configuration entity has complex permissions, you might
* need an access control handling, implementing
- * \Drupal\Core\Entity\EntityAccessControlHandlerInterface, but most entities
- * can just use the 'admin_permission' annotation instead. Note that if you
- * are creating your own access control handler, you should override the
- * checkAccess() and checkCreateAccess() methods, not access().
+ * \Drupal\Core\Entity\EntityAccessControlHandlerInterface, but most
+ * entities can just use the 'admin_permission' annotation property
+ * instead. Note that if you are creating your own access control handler,
+ * you should override the checkAccess() and checkCreateAccess() methods,
+ * not access().
* - storage: A class implementing
* \Drupal\Core\Entity\EntityStorageInterface. If not specified, content
* entities will use \Drupal\Core\Entity\Sql\SqlContentEntityStorage, and
* - delete-form: Confirmation form to delete the entity.
* - edit-form: Editing form.
* - Other link types specific to your entity type can also be defined.
- * - If your content entity is fieldable, provide 'field_ui_base_route'
- * annotation, giving the name of the route that the Manage Fields, Manage
- * Display, and Manage Form Display pages from the Field UI module will be
- * attached to. This is usually the bundle settings edit page, or an entity
- * type settings page if there are no bundles.
+ * - If your content entity is fieldable, provide the 'field_ui_base_route'
+ * annotation property, giving the name of the route that the Manage Fields,
+ * Manage Display, and Manage Form Display pages from the Field UI module
+ * will be attached to. This is usually the bundle settings edit page, or an
+ * entity type settings page if there are no bundles.
* - If your content entity has bundles, you will also need to define a second
* plugin to handle the bundles. This plugin is itself a configuration entity
* type, so follow the steps here to define it. The machine name ('id'
- * annotation) of this configuration entity class goes into the
- * 'bundle_entity_type' annotation on the entity type class. For example, for
- * the Node entity, the bundle class is \Drupal\node\Entity\NodeType, whose
- * machine name is 'node_type'. This is the annotation value for
- * 'bundle_entity_type' on the \Drupal\node\Entity\Node class. Also, the
- * bundle config entity type annotation must have a 'bundle_of' entry,
+ * annotation property) of this configuration entity class goes into the
+ * 'bundle_entity_type' annotation property on the entity type class. For
+ * example, for the Node entity, the bundle class is
+ * \Drupal\node\Entity\NodeType, whose machine name is 'node_type'. This is
+ * the annotation property 'bundle_entity_type' on the
+ * \Drupal\node\Entity\Node class. Also, the
+ * bundle config entity type annotation must have a 'bundle_of' property,
* giving the machine name of the entity type it is acting as a bundle for.
* These machine names are considered permanent, they may not be renamed.

- * \Drupal\node\Entity\Node (content) and \Drupal\user\Entity\Role
