Detailed Description

3 element geodetic vector

3 double precision numbers representing a vector in a WGS84 based geodetic space. Longitude increases east.

Constructor & Destructor Documentation

gvector::gvector ( )

inline

{}

gvector::gvector ( double  tlat, double  tlon, double  th  )

inline

                                                 {
        lat = tlat;
        lon = tlon;
        h = th;
    }

Member Function Documentation

json11::Json gvector::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 {
            { "lat" , lat },
            { "lon" , lon },
            { "h"   , h }
        };
    }

void gvector::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["lat"].is_null())    lat = parsed["lat"].number_value();
            if(!parsed["lon"].is_null())    lon = parsed["lon"].number_value();
            if(!parsed["h"].is_null())      h = parsed["h"].number_value();
        } else  {
            cerr<<"ERROR: <"<<error<<">"<<endl;
        }
        return;
    }
