Question

Is there a way to make a class method accessible in V8?

How can I make a class method accessible in a V8 context?

I am trying to achieve something like the line below, but it's not working because lambda with captures cannot be treated as a function pointer.

Global()->Set("foo",v8::FunctionTemplate::New([this](const v8::Arguments &args) -> v8::Handle<v8::Value>{this->foo()}; return v8::Undefined()));

I'm not talking about exposing literal types like struct Point {int x,y}, but specifically about exposing a class method or a simple callable object.

This is how I managed to make it happen.

context->Global()->Set(v8::String::New("_this"),v8::External::Wrap(this));
context->Global()->Set(v8::String::New("foo"),v8::FunctionTemplate::New(
    [](const v8::Arguments  &args) -> v8::Handle<v8::Value>{
         reinterpret_cast<Foo*>(reinterpret_cast<v8::External*>(*(args.This()->Get(v8::String::New("engine"))))->Value())->foo();
         return v8::Undefined();
})->GetFunction());
