### 3.2.16 break-alignment-interface

The object that performs break alignment. See break-aligned-interface.

#### User settable properties:

> `break-align-orders` (vector)

>   Defines the order in which prefatory matter (clefs, key signatures) appears. The format is a vector of length 3, where each element is one order for end-of-line, middle of line, and start-of-line, respectively. An order is a list of symbols.

>   For example, clefs are put after key signatures by setting

#### Internal properties:

> `positioning-done` (boolean)

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