Deleting crawls

Call the CasCrawler.deleteCrawl() method to delete an existing crawl.

The syntax of the method is: 

CasCrawler.deleteCrawl(CrawlId crawlId)

The crawlId parameter is a CrawlId object that contains the name of the crawl to be deleted.

Note

You cannot delete a crawl that is running.

To delete a crawl:

  1. Make sure that you have created a connection to the CAS Server. (A CasCrawler object named crawler is used in this example.)

  2. Set the name for the crawl to be deleted by first instantiating a CrawlId object and then setting Id in the constructor.

    For example: 

    // Create a new crawl Id with the name set to Demo.
CrawlId crawlId = new CrawlId("Demo");

  3. Call the CasCrawler.deleteCrawl() method with the CrawlId object. To catch exceptions, use a try block with the appropriate catch clauses, as in this example: 

    try {
   crawler.deleteCrawl(crawlId);
}
catch (CrawlNotFoundException e) {
   System.out.println(e.getLocalizedMessage());
}

If the CasCrawler.deleteCrawl() method fails, it throws an exception:

As shown in step 3, use a try block to catch these exceptions.
