      request - The request
      responseProvider - Downstream flow, runs inside the filters
      Returns:

    • fulfillArguments

      protected ExecutionFlow<RouteMatch<?>> fulfillArguments(RouteMatch<?> routeMatch, HttpRequest<?> request)
      Fulfill the arguments of the given route with data from the request. If necessary, this also waits for body data to be available, if there are arguments that need immediate binding.
      Note that in some cases some arguments may still be unsatisfied after this, if they are missing and are Optional. They are satisfied with Optional.empty() later.
      Parameters:
      routeMatch - The route match to fulfill
      request - The request
      Returns:
      The fulfilled route match, after all necessary data is available
