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;
      std::ostream::fmtflags savedFlags = out.setf(std::ios_base::dec | std::ios_base::right);
      Int savedPrec = out.precision(10);
      Int savedWidth = out.width(13);
      const Int dof=qs[0].size();

// this is a hack, as under gcc the flags don't appear to stay set after an output op (!?)
#define setflags \
      out.setf(std::ios_base::dec | std::ios_base::right); \
      out.precision(10); \
      out.width(13); 

      setflags;
      for(Int i=0; i<qs.size(); i++) {
	Vector q(qs[i]);
	Time t(times[i]);
