SetFinalizationCallback()

void SetFinalizationCallback	(	void *	parameter,
		WeakCallbackInfo< void >::Callback	callback
	)

Adds a finalization callback to the handle. The type of this callback is similar to WeakCallbackType::kInternalFields, i.e., it will pass the parameter and the first two internal fields of the object.

The callback is then supposed to reset the handle in the callback. No further V8 API may be called in this callback. In case additional work involving V8 needs to be done, a second callback can be scheduled using WeakCallbackInfo<void>::SetSecondPassCallback.
