[Back to this one year later :D]
I defined a new public member on v8::Function called 'GetData' that returns
the data argument specified when the function was created. Seems to be
working fine, here's the code in case someone wants to give it a quick
glance:
*v8::Local<v8::Value> Function::GetData() const { i::Handle<i::JSReceiver>
self = Utils::OpenHandle(this); i::Isolate* isolate = self->GetIsolate();
if(self->IsJSFunction()) { i::Handle<i::JSFunction> jsf =
i::Handle<i::JSFunction>::cast(self); i::SharedFunctionInfo sfi =
jsf->shared(); if(sfi.IsApiFunction()) { i::FunctionTemplateInfo
fti = sfi.get_api_func_data(); i::CallHandlerInfo chi =
i::CallHandlerInfo::cast(fti.call_code()); i::Object o = chi.data();
i::Handle<i::Object> ho = i::Handle<i::Object>(o, isolate); return
ToApiHandle<v8::Value>(ho); } } return
v8::Undefined(reinterpret_cast<v8::Isolate*>(isolate));}*
It is very verbose on purpose. I will submit a CL soon, I am reading the
requirements :)
Best,
Alex.
