        Response<?> apply​(R resource)
                   throws AuthException,
                          BadRequestException,
                          ResourceConflictException,
                          Exception
        Process the view operation by reading from the resource.

        The value of the returned response is automatically converted to JSON unless it is a BinaryResult.

        The returned response defines the status code that is returned to the client. For RestReadViews this is usually 200 OK, but other 2XX or 3XX status codes are also possible (e.g. Response.Redirect can be returned for 302 Found).

        Throwing a subclass of RestApiException results in a 4XX response to the client. For any other exception the client will get a 500 Internal Server Error response.

        Parameters:
        resource - resource to read
        Returns:
        response to return to the client
        Throws:
        AuthException - the caller is not permitted to access this view.
        BadRequestException - the request was incorrectly specified and cannot be handled by this view.
        ResourceConflictException - the resource state does not permit this view to make the changes at this time.
        Exception - the implementation of the view failed. The exception will be logged and HTTP 500 Internal Server Error will be returned to the client.
