Class BecauseServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          net.myrrix.web.servlets.AbstractMyrrixServlet
              net.myrrix.web.servlets.BecauseServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public final class BecauseServlet
extends AbstractMyrrixServlet

Responds to a GET request to /because/[userID]/[itemID]?howMany=n, and in turn calls ItemBasedRecommender.recommendedBecause(long, long, int). If howMany is not specified, defaults to AbstractMyrrixServlet.DEFAULT_HOW_MANY.

Outputs item/score pairs in CSV or JSON format, like RecommendServlet does.
