All Implemented Interfaces:

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

public final class EstimateServlet
extends AbstractMyrrixServlet

Responds to a GET request to /estimate/[userID]/[itemID] and in turn calls Recommender.estimatePreference(long, long).

Outputs the result of the method call as a value on one line.

This servlet can also compute several estimates at once. Send a GET request to /estimate/[userID]/[itemID1](/[itemID2]/...). The output are estimates, in the same order as the item ID, one per line.
