Same name and namespace in other branches

1. 8 core/modules/views/views.api.php \hook_field_views_data_alter()
2. 10 core/modules/views/views.api.php \hook_field_views_data_alter()

Alter the Views data for a single Field API field.

This is called on all modules even if there is no hook_field_views_data() implementation for the field, and therefore may be used to alter the default data that views_field_default_views_data() supplies for the field storage.

Parameters

array $data: The views data for the field storage. This has the same format as the return value of hook_views_data().

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