All Implemented Interfaces:

ActivityManager

public class ActivityManagerImple
extends Object
implements ActivityManager

The activity manager is the way in which an HLS can register itself with the activity service. This allows it to be informed of the lifecycle of activities and to augment that lifecyle and associated context. An HLS can be associated with all threads (globally) or with only a specific thread (locally).
