getQueryParameter

public static <X,P extends MessageQueryParameter<X>,R extends RequestBody,M extends MessageParameters> X getQueryParameter(HandlerRequest<R> request,
                                                                                                                           Class<P> queryParameterClass)
                                                                                                                    throws RestHandlerException
