2. 10 core/lib/Drupal/Core/Field/FormatterBase.php \Drupal\Core\Field\FormatterBase::prepareView()

Allows formatters to load information for field values being displayed.

This should be used when a formatter needs to load additional information from the database in order to render a field, for example a reference field that displays properties of the referenced entities such as name or type.

This method operates on multiple entities. The $entities_items parameter is an array keyed by entity ID. For performance reasons, information for all involved entities should be loaded in a single query where possible.

Changes or additions to field values are done by directly altering the items.

Parameters

\Drupal\Core\Field\FieldItemListInterface[] $entities_items: An array with the field values from the multiple entities being rendered.
