Member Function Documentation

json11::Json tlestruc::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 {
            { "utc" , utc },
            { "name" , name },
            { "snumber" , snumber },

void tlestruc::from_json ( const string &  js )

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
