public abstract class TrackableManagerListener<TManager> : MessageListener where TManager : MonoBehaviour

Type Parameters

Name	Description
TManager	The event sender type. This should be an AR Foundation trackable manager.

Remarks

TManager is expected to be an AR Foundation trackable manager, but the current version of AR Foundation lacks a shared interface for trackables-changed events. For now the best we can do is bind to MonoBehaviour as a base class.
