public static ContentEntityBase::baseFieldDefinitions(EntityTypeInterface $entity_type)
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:
$fields['name'] = BaseFieldDefinition::create('string') ->setLabel(t('Name'));
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.
Parameters
\Drupal\Core\Entity\EntityTypeInterface $entity_type: The entity type definition. Useful when a single class is used for multiple, possibly dynamic entity types.
Return value
\Drupal\Core\Field\FieldDefinitionInterface[] An array of base field definitions for the entity type, keyed by field name.
Overrides FieldableEntityInterface::baseFieldDefinitions
