Function Documentation

operator<<()

std::ostream& operator<<	(	std::ostream &	os,
		const Vec3D &	a
	)

Adds all elements of the vector to an output stream. NB: this is a global function and a friend of the Vec3D class!

Parameters

[in]	os	the output stream,
[in]	a	The vector of interest

Returns

the output stream with vector elements added

{
    os << a.X << ' ' << a.Y << ' ' << a.Z;
    return os;
}

operator>>()

std::istream& operator>>	(	std::istream &	is,
		Vec3D &	a
	)

Reads all elements of a given vector from an input stream. NB: this is a global function and a friend of the Vec3D class!

Parameters

[in,out]	is	the input stream
[in,out]	a	the vector to be read in

Returns

the input stream from which the vector elements were read

{
    //TW: clearing the stream avoids the nasty problem that the failbit is set to true if numbers below DBL_MIN=1e-308 are read.
    is >> a.X;
    if (is.fail()) {
        logger(VERBOSE,"Failed to read x-value %", a.X);
        //a.X = 0;
        is.clear();
    }
    is >> a.Y;
    if (is.fail()) {
        logger(VERBOSE,"Failed to read y-value %", a.Y);
        //a.Y = 0;
        is.clear();
    }
    is >> a.Z;
    if (is.fail()) {
        logger(VERBOSE,"Failed to read z-value %", a.Z);
        //a.Z = 0;
        is.clear();
    }
    return is;
