Class ActivityTracker

java.lang.Object

org.apache.oodt.commons.activity.ActivityTracker

public class ActivityTracker
extends Object

Tracker of activities. This is the main class applications use to keep track activities. To track an activity, call the createActivity() method to generate a new Activity, then log Incidents against it with the Activity.log(org.apache.oodt.commons.activity.Incident) method. Finally, top the activity with Activity.stop().

The ActivityTracker generates activities using an ActivityFactory. It configures the factory by examining the system properties. The property org.apache.oodt.commons.activity.factories (or the activity.factories property for those that prefer an abbreviated name and the prior one isn't defined) is a comma- (or vertical bar-) seperated list of class names. Each class is expected to implement the ActivityFactory interface. If there are none (or neither property is defined), then a special null factory is used that throws away all incidents. If more than one's defined, then a special factory is used that multiplexes all incidents to each one.
