      inner - (undocumented)
      Returns:
      (undocumented)

    • headerValue

      public <T> RouteAdapter headerValue(Function<HttpHeader,Optional<T>> f, Function<T,Route> inner)
      Extracts an HTTP header value using the given function. If the function result is undefined for all headers the request is rejected with an empty rejection set. If the given function throws an exception the request is rejected with a MalformedHeaderRejection.
      Parameters:
      f - (undocumented)
      inner - (undocumented)
      Returns:

    • headerValueByType

      public <T extends HttpHeader> RouteAdapter headerValueByType(Class<T> t, Function<T,Route> inner)
      Extracts the first HTTP request header of the given type. If no header with a matching type is found the request is rejected with a MissingHeaderRejection.
      Parameters:
      t - (undocumented)
