Detailed Description

Magnetic Torque Rod structure: z axis is aligned with rod.

Member Function Documentation

json11::Json mtrstruc::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<float> v_npoly = vector<float>(npoly, npoly+sizeof(npoly)/sizeof(npoly[0]));
        vector<float> v_ppoly = vector<float>(ppoly, npoly+sizeof(ppoly)/sizeof(ppoly[0]));
        return json11::Json::object {
            { "align" , align },

        };
    }

void mtrstruc::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
