net.myrrix.web.servlets
Class PreferenceServlet

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

All Implemented Interfaces:

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

public final class PreferenceServlet
extends AbstractMyrrixServlet

Responds to a POST request to /pref/[userID]/[itemID] and in turn calls MyrrixRecommender.setPreference(long, long, float). If the request body is empty, the value is 1.0, otherwise the value in the request body's first line is used.

Also responds to a DELETE request to the same path, with the same defaults. This corresponds to calling MyrrixRecommender.removePreference(long, long) instead.
