Detailed Description

3 element generic row vector

3 double precision numbers representing a 3 element row major vector.

Constructor & Destructor Documentation

rvector::rvector ( )

inline

{}

rvector::rvector ( double  d0, double  d1, double  d2  )

inline

                                             {
        col[0] = d0;
        col[1] = d1;
        col[2] = d2;
    }

Member Function Documentation

json11::Json rvector::to_json ( ) const

inline

Convert class contents to JSON object.

Returns a json11 JSON object of the class

Returns

A json11 JSON object containing every member variable within the class

                               {
        vector<double> v_col = vector<double>(col, col+sizeof(col)/sizeof(col[0]));
        return json11::Json::object {
            { "col" , v_col }
        };
    }

void rvector::from_json ( const string &  s )

inline

Set class contents from JSON string.

Parses the provided JSON-formatted string and sets the class data. String should be formatted like the string returned from to_json()

Parameters

s	JSON-formatted string to set class contents to

Returns

n/a

                                    {
        string error;
        json11::Json parsed = json11::Json::parse(s,error);
        if(error.empty()) {
            auto p_col = parsed["col"].array_items();
            for(size_t i = 0; i != p_col.size(); ++i) {
                if(!p_col[i].is_null()) col[i] = p_col[i].number_value();
            }
        } else  {
            cerr<<"ERROR: <"<<error<<">"<<endl;
        }
        return;
