ExplicitMapper

Map items by explicit index pairs or sequential index order.

When no pairs are specified, maps by index: start[0]→end[0], start[1]→end[1], etc. Extra items on either side become creations or destructions. When pairs are specified, maps exactly as given. Unmentioned items become creations or destructions.

Constructor

ExplicitMapper(pairs: Optional[Sequence[Tuple[int, int]]] = None)

Parameters

pairs: Optional list of (start_index, end_index) tuples. If None, maps sequentially by index.

Methods

map(
    start_items: List[T],
    end_items: List[T],
    get_position: Callable[[T], Point2D]
) -> List[Match[T]]
