Examples of org.apache.sling.api.resource.ResourceNotFoundException

org.apache.sling.api.resource.ResourceNotFoundException
An Exception that causes Sling to return a 404 (NOT FOUND) status code. This exception should not be caught but rather let be handed up the call stack up to the Sling error and exception handling.
The advantage of using this exception over the HttpServletResponse.sendError methods is that the request can be aborted immediately all the way up in the call stack and that in addition to the status code and an optional message a Throwable may be supplied providing more information.

            Authorizable item = resource.adaptTo(Authorizable.class);
            if (item == null) {
                String msg = "Missing source " + resource.getPath()
                    + " for delete";
                response.setStatus(HttpServletResponse.SC_NOT_FOUND, msg);
                throw new ResourceNotFoundException(msg);
            } else {
                if (item instanceof User) {
                    deleteUser(session, item.getID(), changes);
                } else if (item instanceof Group) {
                    deleteGroup(session, item.getID(), changes);
