### 3.2.130 tie-column-interface

Object that sets directions of multiple ties in a tied chord.

#### User settable properties:

> `tie-configuration` (list)

>   List of `(position . dir)` pairs, indicating the desired tie configuration, where position is the offset from the center of the staff in staff space and dir indicates the direction of the tie (`1`=>up, `-1`=>down, `0`=>center). A non-pair entry in the list causes the corresponding tie to be formatted automatically.

#### Internal properties:

> `positioning-done` (boolean)

>   Used to signal that a positioning element did its job. This ensures that a positioning is only done once.

> `ties` (array of grobs)

>   A grob array of `Tie` objects.
