Constructor Summary

ActivityEvent()
Like the default RTEvent constructor, which uses the current (RT)Thread as the source.

ActivityEvent(Activity source)
Constructs an ActivityEvent object with the specified source activity, set as the source of this event.

ActivityEvent(Activity source, long ts)
Create a new event with both source and time set.

ActivityEvent(Activity source, long ts, Timebase timebase)
Constructs an activity-event object with the specified source object and time-stamp with respect to the specified time-base.

ActivityEvent(long ts)
The new event gets the time stamp according to ts.
