public class ActivityManager
extends java.lang.Thread
The ActivityManager is responsible for scheduling and running timed activities that perform data processing and animation.
The ActivityManager runs in its own separate thread of execution, and one instance is used to schedule activities from any number of currently active visualizations. The class is implemented as a singleton; the single instance of this class is interacted with through static methods. These methods are called by an Activity's run methods, and so are made only package visible here.
Activity instances can be scheduled by using their
Activity.run(),
Activity.runAt(long), and
Activity.runAfter(Activity)
methods. These will automatically call the
appropriate methods with the ActivityManager.
For Action instances, one can also register
the actions with a Visualization and use the
visualizations provided run methods to launch Actions in a
convenient fashion. The interface, which is backed by an ActivityMap
instance, also provides a useful level of indirection, allowing actions
to be changed dynamically without changes to code in other locations.
