 org.archive.crawler.postprocessor.WaitEvaluator
All known Subclasses: org.archive.crawler.postprocessor.ContentBasedWaitEvaluator,
| WaitEvaluator | | public class WaitEvaluator extends Processor implements AdaptiveRevisitAttributeConstants(Code) | | A processor that determines when a URI should be revisited next. Does
not account for DNS and robots.txt expiration. That should be
handled seperately by the Frontiers.

| ATTR_CHANGED_FACTOR | | final public static String ATTR_CHANGED_FACTOR(Code) | | Factor decrease on wait when changed
|
| ATTR_DEFAULT_WAIT_INTERVAL | | final public static String ATTR_DEFAULT_WAIT_INTERVAL(Code) | | Fixed wait time for 'unknown' change status. I.e. wait time for URIs
whose content change detection is not available.
|

|
| ATTR_MAX_WAIT_INTERVAL | | final public static String ATTR_MAX_WAIT_INTERVAL(Code) | | Maximum wait between visits
|
| ATTR_MIN_WAIT_INTERVAL | | final public static String ATTR_MIN_WAIT_INTERVAL(Code) | | Minimum wait between visits
|
| ATTR_UNCHANGED_FACTOR | | final public static String ATTR_UNCHANGED_FACTOR(Code) | | Factor increase on wait when unchanged
|
| ATTR_USE_OVERDUE_TIME | | final public static String ATTR_USE_OVERDUE_TIME(Code) | | Indicates if the amount of time the URI was overdue should be added
to the wait time before the new wait time is calculated.
