```kotlin
public class WindowFold(public val state: FoldState, public val orientation: FoldOrientation)
```

Represents a single physical fold or hinge intersecting the window.

A `WindowFold` describes a geometric screen feature that actively crosses the bounds of the
current window. It maps directly to the state of underlying hardware hinge sensors.

#### Parameters
