Member Function Documentation

json11::Json rwstruc::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 {
            { "align" , align },
            { "mom"   , mom },
            { "mxomg" , mxomg },
            { "mxalp" , mxalp },
            { "tc"  , tc },
            { "omg"   , omg },
            { "alp"   , alp },
            { "romg"  , romg },
            { "ralp"  , ralp },
        };
    }

void rwstruc::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
