Class RecommendToAnonymousServlet

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

net.myrrix.web.servlets.AbstractMyrrixServlet

net.myrrix.web.servlets.RecommendToAnonymousServlet

All Implemented Interfaces:

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

public final class RecommendToAnonymousServlet
extends AbstractMyrrixServlet

Responds to a GET request to /recommendToAnonymous/[itemID1(=value1)](/[itemID2(=value2)]/...)?howMany=n[&rescorerParams=...], and in turn calls MyrrixRecommender.recommendToAnonymous(long[], float[], int, IDRescorer) with the supplied values. That is, 1 or more item IDs are supplied, which may each optionally correspond to a value or else default to 1. If howMany is not specified, defaults to AbstractMyrrixServlet.DEFAULT_HOW_MANY.

Unknown item IDs are ignored, unless all are unknown, in which case a HttpServletResponse.SC_BAD_REQUEST status is returned.

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