Enumerate all properties in Mozilla JSAPI

I want to programmatically list all properties of JS object from C++ code (I am using Mozilla's JSAPI). I know I can go up the prototype chain 开发者_如何学运维with JS_GetPrototype, then enumerate each object's own properties with JS_Enumerate. Is there a simpler way to do this?

I don't think there is. The code implementing property enumeration for JavaScript (function js_ValueToIterator()) uses highly optimized iterators. I don't see these iterators being made accessible to JSAPI anywhere.
