Detailed Description

Payload (PLOAD) structure.

You can define up to MAXPLOADKEYCNT keys by giving them unique names. You can then set double precision values for these keys in the dynamic structure.

Member Function Documentation

json11::Json ploadstruc::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<uint16_t> v_keyidx = vector<uint16_t>(keyidx, keyidx+MAXPLOADKEYCNT);
        vector<float> v_keyval = vector<float>(keyval, keyval+MAXPLOADKEYCNT);
        return json11::Json::object {
            { "key_cnt", key_cnt },
            { "keyidx" , v_keyidx },
            { "keyval" , v_keyval }
        };
    }

void ploadstruc::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
