An implementation of this is referenced in the crawl order and loaded when the crawl begins. <p>It will be given a reference to the relevant CrawlController. The CrawlController will contain any additional configuration information needed. <p>Any class that implements this interface can be specified as a statistics tracker in a crawl order. The CrawlController will then create and initialize a copy of it and call it's start() method. <p>This interface also specifies several methods to access data that the CrawlController or the URIFrontier may be interested in at run time but do not want to have keep track of for themselves. <A HREF="../../../../org/archive/crawler/framework/AbstractTracker.html" title="class in org.archive.crawler.framework"><CODE>AbstractTracker</CODE></A> implements these. If there are more then one StatisticsTracking classes defined in the crawl order only the first one will be used to access this data. <p>It is recommended that it register for <A HREF="../../../../org/archive/crawler/event/CrawlStatusListener.html" title="interface in org.archive.crawler.event"><CODE>CrawlStatus</CODE></A> events and <A HREF="../../../../org/archive/crawler/event/CrawlURIDispositionListener.html" title="interface in org.archive.crawler.event"><CODE>CrawlURIDisposition</CODE></A> events to be able to properly monitor a crawl.
