示例1: invalid_argument
if (qs.size() < 2)
throw std::invalid_argument(Exception(String("joint waypoint text file must contain at least 2 'waypoint' vectors")));
init(qs,times,deltas);
}
else { // output
std::ostringstream out;
// comment header
out << "# Joint waypoint trajectory [joint positions & times (at-end)]" << std::endl;
out << "# the following line should be 'absolute' for absolute qi's & t values or 'relative' if the vectors represent inter-waypoint deltas dqi's & dt" << std::endl;
out << "absolute" << std::endl; // not "relative"
out << "# q0 q1 ... qn t" << std::endl;

Int savedPrec = out.precision(10);

// this is a hack, as under gcc the flags don't appear to stay set after an output op (!?)
