Retrieving code and scope from a function

[Seiji Sam Lee]

Hi everybody:

I am building a bson like library (bjason), and I would like encode/decode functions.

Bson allow en/decode code and its scope, but I don't know to get the code nor scope.

Well, code is easy, with ToString(), but in others examples (mainly from mongodb code) it seems that code and scope is extracted using Get(code_sym) and Get(scope_sym) over the Object, with code and scope_sym persistent handles to "code" and "scope".

For example: https://github.com/akdubya/BSON.js/blob/fed4678b32557199570d0af0d850bff65943eefe/src/encode.cc line 91

Can anybody explain me this?

By the way, is it possible to get the scope of a function? that is, bindings done?

For example:

var a=1;

var fx=function(v) { return v+a; }

The scope of fx is: { a }, am I wrong?

Thanks in advance.
