That wasn't what I had proposed. My suggestion was to use an interface, as always, but made this API real clean, expressing the minimum the rest of the code needs from a scoring plugin, removing assumptions about its implementation. Then I've proposed to have an abstract class, implementing this interface, with a skeleton for any class which works "distributing score to outlinks". So we would have the best of both worlds: People creating new "PageRank" algorithms wouldn't need to reimplement anuything, they would just subclass the abstract class. And people like you and me would directly implement the interface (or use a different abstract class if there's common logic to share). My boss put all of this on hold, but I'd like to implement this idea in a near future and try to have it included in Nutch. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
