Class TemplateRoute

  • All Implemented Interfaces:
    Uniform

    public class TemplateRoute
    extends Route
    Filter scoring the affinity of calls with the attached Restlet. The score is used by an associated Router in order to determine the most appropriate Restlet for a given call. The routing is based on a reference template.

    Concurrency note: instances of this class or its subclasses can be invoked by several threads at the same time and therefore must be thread-safe. You should be especially careful when storing state in member variables.
