I want to expose some classes to javascript so users can create
instances of them. From what I can piece together the code might look
something like so
Handle<FunctionTemplate> myObjectCtorFunction =
FunctionTemplate::New(MyObjectCtorCallback);
Handle<ObjectTemplate> myObjectInstanceTempl = myObjectCtorFunction-
>InstanceTemplate();
// setup properties and internal fields on myObjectInstanceTempl
// make ctor available to js
globals->Set("MyObject", myObjectCtorFunction);
Handle<Value> MyObjectCtorCallback(const Arguments& args)
{
// args.IsConstructCall is true if used as ctor ?
// args.Holder() is the already created instance?
// so something like
if (args.IsConstructCall()) {
// create c++ object
// set internal field of args.Holder() with c++ object
return args.Holder()
}
return Undefined();
}
Is this correct? And what about destruction, how do I make sure I can
destroy my c++ object when the js object is collected?
