(Launching, pausing etc.) Included in this is keeping track of the total time spent (actually) crawling. Several methods to access the time started, finished etc. are provided. <p> To handle the thread work the class implements the CrawlStatusListener and uses it's events to pause, resume and stop logging of statistics. The run() method will call logActivity() at intervals specified in the crawl order. <p> Implementation of logActivity (the actual logging) as well as listening for CrawlURIDisposition events is not addressed.<P><P><DL><DT><B>Author:</B></DT> <DD>Kristinn Sigurdsson</DD><DT><B>See Also:</B><DD><A HREF="../../../../org/archive/crawler/framework/StatisticsTracking.html" title="interface in
