public class DefaultUsageService
extends AbstractService
implements UsageService

Default service for tracking anonymous usage statistics.

Please note that that this implementation is not thread safe. It is up to the caller to ensure that multiple threads do not attempt to modify statistics at the same time. One way to do that (but not the only way) is to only call increment(Object) from the event dispatch thread (i.e., when ThreadService.isDispatchThread() returns true). And one easy way to accomplish that is by calling the UsageService only from event handler methods.
