interface QueryAccessHandlerInterface in Entity API 8
Query access handlers control access to entities in queries.
An entity defines a query access handler in its annotation: @code query_access = "\Drupal\entity\QueryAccess\QueryAccessHandler" @code The handler builds a set of conditions which are then applied to a query to filter it. For example, if the user #22 only has access to view their own entities, a uid = '22' condition will be built and applied.
The following query types are supported:
- Entity queries with the $entity_type_id . '_access' tag.
- Views queries.
