How to iterate over a V8 key-value object in C++ (get a list of the object's keys)?

Question

C++ / C#

An object of type key-value comes from the callback. How to iterate over such an object in a C++ module? That is, getting the value of the key at each iteration? How to get a value by key is clear:

// retval is Local<Object>
retval->Get(String::New("keyname"));

But how to get a list of keys - I can’t google.

Answer 1

As far as I understand it is possible to call GetOwnPropertyNames and move from there.
