CustomFollowController

Interface that can be implemented on the platform to create custom controller for parameter tracking. To add a controller to a camera, you need to implement this interface and create a FollowController object passing an object that implements this interface as an argument.

Methods
fun availableValues(): EnumSet<FollowValue>

Set of value types that this controller can manage.

Returns
fun requestValues(values: EnumSet<FollowValue>): Unit

Tells the controller which values it provides are in use. This frees up the resources associated with calculating unused values. The method can be called multiple times with different values, in which case the last one is considered relevant.

Parameters
values
Returns
fun setNewValuesNotifier(notifier: NewValuesNotifier?): Unit

Installs a notifier that notifies about new values. The notifier must be stored in the implemented controller

Parameters

fun coordinates(): GeoPoint?
