// private - только в коде основоного (родительского) класса
$result = $this->compose_move_map( $previous_id, $product_id, $next_id, $anchor_positions ): object;

$previous_id(int) (обязательный)

ID of the product immediately before the target position, or 0 when moving to the start.

$product_id(int) (обязательный)

ID of the product being repositioned.

$next_id(int) (обязательный)

ID of the product immediately after the target position, or 0 when moving to the end.

$anchor_positions(array<int,int>) (обязательный)

Map of product ID → current menu_order for the three anchor products.
