mapRouteResultWith

Description

Changes the message the inner route sends to the responder.

The mapRouteResult directive is used as a building block for Custom Directives to transform the RouteResult coming back from the inner route. It's similar to the mapRouteResult directive but returning a CompletionStage instead of a result immediately, which may be useful for longer running transformations.

See Transforming the RouteResult for similar directives.
