public DriverRemoteTraversal(final ResultSet rs, final Client client, final boolean attach, final Optional<Configuration> conf) {
    // attaching is really just for testing purposes. it doesn't make sense in any real-world scenario as it would
    // require that the client have access to the Graph instance that produced the result. tests need that
    // attachment process to properly execute in full hence this little hack.
    if (attach) {

        final Graph graph = ((Supplier<Graph>) conf.get().getProperty(GREMLIN_REMOTE + "attachment")).get();
