Interface RouteGroup

public interface RouteGroup

A bundle of routes mounted underneath /data/group-name/*

Each route will be activated when a web request that matches the route's method and path comes into the Ignition webserver. The route handler will then be called to provide a response. The response can then be rendered to a string via the response renderer, if desired. Some examples:

Mounts a text/plain response of "hello, world" at /data/module-id/hello_world 

     routeGroup.newRoute("/hello_world")
       .handler((request, response) -> "Hello, world!")
       .accessControl(AccessControlStrategy.OPEN_ROUTE)
       .mount();

Mounts a json response that serializes a list of widget objects using GSON 

     routeGroup.newRoute("/widgets")
       .handler(this::getWidgetList)
       .renderer(gson::toJson)
       .type("application/json")
       .requirePermission(PermissionType.READ)
       .mount();

Mounts a json response that fetches a specific object, using url parameter matching. For example, the URL request /data/module-id/widget/8271 would fetch widget with id=8271 

     routeGroup.newRoute("/widget/:id")
       .handler((request, response) -> findWidget(request.getParameter("id"))
       .renderer(gson::toJson)
       .type("application/json")
       .requirePermission(PermissionType.READ)
       .mount();
