1. 8 core/modules/views/src/Plugin/views/field/Field.php \Drupal\views\Plugin\views\field\Field::addSelfTokens()

Add any special tokens this field might use for itself.

This method is intended to be overridden by items that generate fields as a list. For example, the field that displays all terms on a node might have tokens for the tid and the term.

By convention, tokens should follow the format of {{ token subtoken }} where token is the field ID and subtoken is the field. If the field ID is terms, then the tokens might be {{ terms__tid }} and {{ terms__name }}.
