CrawlEventArgs, UriIncludeEventArgs

Ruya's Crawler provides event-based callback mechanism during crawl to allow clients to have more control over which urls are crawled. The events use this object for event communication.

  # Client side event handler
  def beforecrawl(caller, eventargs):
     # Some process
     # ...

     # Url is already crawled before (might be determined based on a simple dictionary caching mechanism)
     eventargs.ignore= False  # Request Ruya to ignore this url during crawl

     # ...

  def aftercrawl(caller, eventargs):
     # Some process
     # ...

     # Some error occurred during saving crawled data (might be a file or database), abort further crawling
     eventargs.cancel= True       # Cancel crawling completely

     # ...
