The MediaPlayerOverlayController defines all the methods that a OverlayController subclass must or can implement to be able to register as an overlay controller with the player. This abstract class implements the KRAdapter interface, so objects should also define a unique string type to register under.

public abstract class MediaPlayerOverlayController : KRAdapter

Public MustInherit Class MediaPlayerOverlayController
	Implements KRAdapter

public ref class MediaPlayerOverlayController abstract : KRAdapter

[<AbstractClassAttribute>]
type MediaPlayerOverlayController =  
    class
        interface KRAdapter
    end
