Alter the Views data on a per field basis.

The Views module's implementation of hook_views_data_alter() invokes this for each field storage, in the module that defines the field type. It is not invoked in other modules.

Unlike hook_field_views_data_alter(), this operates on the whole of the views data. This allows a field type to add data that concerns its fields in other tables, which would not yet be defined at the point when hook_field_views_data() and hook_field_views_data_alter() are invoked. For example, entity_reference adds reverse relationships on the tables for the entities which are referenced by entity_reference fields.

(Note: this is weirdly named so as not to conflict with hook_field_views_data_alter().)

Parameters

array $data: The views data.

\Drupal\field\FieldStorageConfigInterface $field: The field storage config entity.
