I know creating an ObjectTemplate and we can do several things to it. But
my question is not about those well-known things.
I want to know how to pass the second parameter.
As the official guide said:
Each function template has an associated object template. This is used to
configure objects created with this function as their constructor.
And the second parameter of ObjectTemplate::New is a constructor typed by
FunctionTemplate.
static Local<ObjectTemplate> New(Isolate *isolate, Local<FunctionTemplate>
constructor = Local<FunctionTemplate>());
That means something like this:
void Constructor(const FunctionCallbackInfo<Value>& args){
// ...}
Local<FunctionTemplate> _constructor = FunctionTemplate::New(isolate,
Constructor);Local<ObjectTemplate> tpl = ObjectTemplate::New(isolate,
_constructor);
Who can give me a demo that how to implement the Constructor function.
I tried this, but failed:
void Constructor(const FunctionCallbackInfo<Value>& args){
Isolate* isolate = args.GetIsolate();
args.This()->Set(String::NewFromUtf8(isolate, "value"),
Number::New(isolate, 233));
args.GetReturnValue().Set(args.This());}
By the way, I know the use case of accessors and so on, I just want to know
how to use the second parameter.
