org.archive.crawler.framework.Processor
   org.archive.crawler.extractor.ChangeEvaluator

ChangeEvaluator
public class ChangeEvaluator extends Processor implements AdaptiveRevisitAttributeConstants(Code)
This processor compares the CrawlURI's current org.archive.crawler.datamodel.CrawlURI.getContentDigest content digest with the one from a previous crawl. If they are equal, then further processing is skipped (going straight to the post processor chain) and the CrawlURI is marked appropriately.
