How to bind a std::function to JavaScript V8?

Question

I just started using JavaScript V8 and compiled a basic example from the Embedder's Guide. Now I want to bind C++ functions to the JavaScript context.

For now I only have a more or less blank class which should handle binding later on.

class Manager
{
public:
    Manager()
    {
        context = Context::New();
    }
    void Bind(string Name, function<Handle<Value>(const Arguments&)> Function)
    {
        // bind the function to the given context
    }
private:
    Persistent<Context> context;
};

How can I bind a std::function object to the JavaScript V8 context?

Answer 1

The parameter type InvocationCallback which is requested by the Set function is a simple typedef.

typedef Handle<Value> (*InvocationCallback)(Arguments const &);

Therefore I had to convert the std::function to a raw function pointer.

void Register(string Name, function<Handle<Value>(Arguments const &)> Function)
{
    InvocationCallback* function = Function.target<InvocationCallback>();
    globals->Set(String::New(Name.c_str()), FunctionTemplate::New(*function));
}
