      Description copied from interface: `javax.servlet.ServletRegistration`
      Adds a servlet mapping with the given URL patterns for the Servlet represented by this ServletRegistration. If any of the specified URL patterns are already mapped to a different Servlet, no updates will be performed. If this method is called multiple times, each successive call adds to the effects of the former. The returned set is not backed by the ServletRegistration object, so changes in the returned set are not reflected in the ServletRegistration object, and vice-versa.

      Parameters:
        `urlPatterns` - The URL patterns that this Servlet should be mapped to

        a (possibly empty) Collection of the currently available mappings of the Servlet represented by this ServletRegistration

    - #### getRunAsRole

          public String getRunAsRole()
