Java Source Code / Java Documentation » Web Crawler » heritrix » org.archive.crawler.frontier   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.archive.crawler.io.CrawlerJournal       org.archive.crawler.frontier.RecoveryJournal RecoveryJournal public class RecoveryJournal extends CrawlerJournal implements FrontierJournal(Code) Helper class for managing a simple Frontier change-events journal which is useful for recovering from crawl problems. By replaying the journal into a new Frontier, its state (at least with respect to URIs alreadyIncluded and in pending queues) will match that of the original Frontier, allowing a pseudo-resume of a previous crawl, at least as far as URI visitation/coverage is concerned. author:    gojomo Field Summary final public static  String F_ADD      final public static  String F_EMIT      final public static  String F_FAILURE      final public static  String F_RESCHEDULE      final public static  String F_SUCCESS      Constructor Summary public   RecoveryJournal(String path, String filename)      Method Summary public synchronized  void added(CrawlURI curi)      public  void emitted(CrawlURI curi)      public  void finishedFailure(CrawlURI curi)      public  void finishedFailure(UURI uuri)      public  void finishedFailure(String u)      public  void finishedSuccess(CrawlURI curi)      public  void finishedSuccess(UURI uuri)      protected  void finishedSuccess(String uuri)      public static  void importRecoverLog(File source, Frontier frontier, boolean retainFailures)      Utility method for scanning a recovery journal and applying it to a Frontier. public  void rescheduled(CrawlURI curi)      Field Detail F_ADD final public static String F_ADD(Code) F_EMIT final public static String F_EMIT(Code) F_FAILURE final public static String F_FAILURE(Code) F_RESCHEDULE final public static String F_RESCHEDULE(Code) F_SUCCESS final public static String F_SUCCESS(Code) Constructor Detail RecoveryJournal public RecoveryJournal(String path, String filename) throws IOException(Code) Create a new recovery journal at the given location Parameters:   path - Directory to make the recovery journal in.
