able to get inner content by utilizing GetJsonValueByPath

[cielavenir]

these will be possible

double max_tool_speed_rot = object->Get<double>("robot_motion_parameters/max_tool_speed_rot");
string ikTypeName = object->Get<string>("robot_motion_parameters/ikTypeName");
map<string, vector<int>> params = object->Get<map<string, vector<int>>>("robot_motion_parameters/int_parameters");

note that we cannot do object->Get<map<string, map<string, vector<int>>>>("robot_motion_parameters");. This is C++ limitation.

We will use GetJsonValueByPath, so we add leading / to field variable (after copying to temporary variable).

1. who is the user of this?
2. so much small std::string copy and creation

[rdiankov]

@cielavenir looks pretty inefficient with creating all these strings on the heap, especially when rapidjson doesn't require std::string

[cielavenir]

well, alternative ideas are:

1. use GetJsonValueByPath only when field contains "/"
2. add a new API named GetPath

[cielavenir]

added GetPath now

@ziyan could you check https://github.com/mujin/controllerclientcpp/blob/savebackup/samples/mujinupdatepulseoffset.cpp#L204 ? /cc @kanbouchou

Should I add GetPath()?

[cielavenir]

btw I realized std::string fieldToConstraintForCallGet = path.substr(1, path.find('/', 1)); is better, please tell me such matter(s) /cc @lazydroid
