Domino REST supports matrix parameters on path segments. Use @MatrixParam to bind values like /movies;lang=en;region=eu to method arguments, keeping them separate from query parameters.
@RequestFactory
public interface MoviesService {
@Path("library/movies/:movieName")
@GET
Movie getMovieByName(@PathParam("movieName") String movieName);
@Path("library/movies")
@GET
List<Movie> listMovies();
@Path("library/movies/:name")
@PUT
@SuccessCodes({200})
void updateMovie(@beanParam @RequestBody Movie movie);
}
Matrix parameters are appended to the path segment they belong to. When combined with other annotations (e.g., @QueryParam, @HeaderParam), Domino REST keeps each binding type separated and renders them in the correct location.
