/**
* Defines the ContentEntityExample entity.
*
* @ingroup content_entity_example
*
* This is the main definition of the entity type. From it, an EntityType object
* is derived. The most important properties in this example are listed below.
*
* id: The unique identifier of this entity type. It follows the pattern
* 'moduleName_xyz' to avoid naming conflicts.
*
* label: Human readable name of the entity type.
*
* handlers: Handler classes are used for different tasks. You can use
* standard handlers provided by Drupal or build your own, most probably derived
* from the ones provided by Drupal. In detail:
*
* - view_builder: we use the standard controller to view an instance. It is
* called when a route lists an '_entity_view' default for the entity type.
* You can see this in the entity.content_entity_example_contact.canonical
* route in the content_entity_example.routing.yml file. The view can be
* manipulated by using the standard Drupal tools in the settings.
*
* - list_builder: We derive our own list builder class from EntityListBuilder
* to control the presentation. If there is a view available for this entity
* from the views module, it overrides the list builder if the "collection"
* key in the links array in the Entity annotation below is changed to the
* path of the View. In this case the entity collection route will give the
* view path.
*
* - form: We derive our own forms to add functionality like additional fields,
* redirects etc. These forms are used when the route specifies an
* '_entity_form' or '_entity_create_access' for the entity type. Depending on
* the suffix (.add/.default/.delete) of the '_entity_form' default in the
* route, the form specified in the annotation is used. The suffix then also
* becomes the $operation parameter to the access handler. We use the
* '.default' suffix for all operations that are not 'delete'.
*
* - access: Our own access controller, where we determine access rights based
* on permissions.
*
* More properties:
*
* - base_table: Define the name of the table used to store the data. Make sure
* it is unique. The schema is automatically determined from the
* BaseFieldDefinitions below. The table is automatically created during
* installation.
*
* - entity_keys: How to access the fields. Specify fields from
* baseFieldDefinitions() which can be used as keys.
*
* - links: Provide links to do standard tasks. The 'edit-form' and
* 'delete-form' links are added to the list built by the
* entityListController. They will show up as action buttons in an additional
* column.
*
* - field_ui_base_route: The route name used by Field UI to attach its
* management pages. Field UI module will attach its Manage Fields,
* Manage Display, and Manage Form Display tabs to this route.
*
* There are many more properties to be used in an entity type definition. For
* a complete overview, please refer to the '\Drupal\Core\Entity\EntityType'
* class definition.
*
* The following construct is the actual definition of the entity type which
* is read and cached. Don't forget to clear cache after changes.
*
* @ContentEntityType(
* id = "content_entity_example_contact",
* label = @Translation("Contact entity"),
* handlers = {
* "view_builder" = "Drupal\Core\Entity\EntityViewBuilder",
* "list_builder" = "Drupal\content_entity_example\Entity\Controller\ContactListBuilder",
* "form" = {
* "default" = "Drupal\content_entity_example\Form\ContactForm",
* "delete" = "Drupal\content_entity_example\Form\ContactDeleteForm",
* },
* "access" = "Drupal\content_entity_example\ContactAccessControlHandler",
* },
* list_cache_contexts = { "user" },
* base_table = "contact",
* admin_permission = "administer contact entity",
* entity_keys = {
* "id" = "id",
* "label" = "name",
* "uuid" = "uuid"
* },
* links = {
* "canonical" = "/content_entity_example_contact/{content_entity_example_contact}",
* "edit-form" = "/content_entity_example_contact/{content_entity_example_contact}/edit",
* "delete-form" = "/contact/{content_entity_example_contact}/delete",
* "collection" = "/content_entity_example_contact/list"
* },
* field_ui_base_route = "content_entity_example.contact_settings",
* )
*
* The 'links' above are defined by their path. For core to find the
* corresponding route, the route name must follow the correct pattern:
*
* entity.<entity_type>.<link_name>
*
* Example: 'entity.content_entity_example_contact.canonical'.
*
* See the routing file at content_entity_example.routing.yml for the
* corresponding implementation.
*
* The Contact class defines methods and fields for the contact entity.
*
* Being derived from the ContentEntityBase class, we can override the methods
* we want. In our case we want to provide access to the standard fields about
* creation and changed time stamps.
*
* Our interface (see ContactInterface) also exposes the EntityOwnerInterface.
* This allows us to provide methods for setting and providing ownership
* information.
*
* The most important part is the definitions of the field properties for this
* entity type. These are of the same type as fields added through the GUI, but
* they can by changed in code. In the definition we can define if the user with
* the rights privileges can influence the presentation (view, edit) of each
* field.
*
* The class also uses the EntityChangedTrait trait which allows it to record
* timestamps of save operations.
