Detailed Description

Quaternion, scalar last, using vector elements.

Can be thought of as vector elements, q1, q2, q3, followed by scalar q4.

Constructor & Destructor Documentation

qlast::qlast ( )

inline

{}

qlast::qlast ( double  tq1, double  tq2, double  tq3, double  tq4  )

inline

                                                          {
        q1 = tq1;

Member Function Documentation

json11::Json qlast::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

                               {
        return json11::Json::object {
            { "q1" , q1 },
            { "q2" , q2 },
            { "q3" , q3 },
            { "q4" , q4 }
        };
    }

void qlast::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()) {
            if(!parsed["q1"].is_null()) q1 = parsed["q1"].number_value();
            if(!parsed["q2"].is_null()) q2 = parsed["q2"].number_value();
            if(!parsed["q3"].is_null()) q3 = parsed["q3"].number_value();
            if(!parsed["q4"].is_null()) q4 = parsed["q4"].number_value();
        } else  {
            cerr<<"ERROR: <"<<error<<">"<<endl;
        }
