I also wrap a C++ global object -- although I don't allow accessors on
it, only on objects inside of it.
However, you can pass to an accessor a data object. See this from v8.h:
void SetAccessor(Handle<String> name,
AccessorGetter getter,
AccessorSetter setter = 0,
Handle<Value> data = Handle<Value>(),
AccessControl settings = DEFAULT,
PropertyAttribute attribute = None);
You can just set data to a v8::External holding your global object.
This would mean that each global object would have to have its own
template, but it will work. You retrieve it from the AccessorInfo
object passed to your accessor, by using the Data() function.
I'm not sure how you'd do it with one template, though, without an
internal field, which apparently doesn't work.
I hope that helps,
Alex
