I'm playing with creating Node.js modules in C++, but I'm stumped on the v8::Arguments class. Lets say I have a Javascript class for sending emails, which has a method with this signature:

```
Mailer::sendEmail(Array recipients, String sender, String message);

```

Which would be called like this:

```
mailer.sendEmail(["joe@gmail.com", "sally@gmail.com"], "fred@gmail.com", "Hi there");

```

Now in C++ land, I have a class function with this signature:

```
SendEmail(const v8::Arguments& args)

```

Which is backing my Mailer::sendEmail method in Javascript land. The SendEmail function will create a new instance of my Emailer class, which itself has a class function with this signature:

```
send(std::list<std::string> recipients, std::string from, std::string message)

```

And this is where I'm lost. I don't know how to take the values from *args*, and convert them into regular C++ types, so I can pass the values to my *send* function. As I understand it, the 3 values passed to Mailer::sendEmail will be available in *args[0]*, *args[1]*, and *args[2]*. I even understand I can do some type checking like `if (!args[0]->IsArray())`, but actually converting *args[0]* to `std::list<std::string>` is what I don't know how to do.

**Edit:** I found a hackish way of doing this, but I still think V8 has some built in methods to handle this in a cleaner way.

```
static Handle<Value> SendEmail(const Arguments& args)
{
    HandleScope scope;

    list<string> values;
    Local<Object> obj = args[0]->ToObject();
    Local<Array> props = obj->GetPropertyNames();

    // Iterate through args[0], adding each element to our list
    for(unsigned int i = 0; i < props->Length(); i++) {
        String::AsciiValue val(obj->Get(i)->ToString());
        values.push_front(string(*val));
    }

    // Display the values in the list for debugging purposes
    for (list<string>::iterator it = values.begin(); it != values.end(); it++) {
        cout << *it << endl;
    }

    return scope.Close(args.This());
}

```
