I found this helper method in a tutorial
<http://www.equals-forty-two.com/templates/post.html> a couple of days ago.
It reinterpret casts a v8::Persistent to a v8::Local, with the intended use
of calling V8 API functions that require a local handle to a context,
without actually having to create a new v8::Local each time:
template <class TypeName>
inline v8::Local<TypeName> ToLocal(const v8::Persistent<TypeName>&
persistent)
{
return
*reinterpret_cast<v8::Local<TypeName>*>(const_cast<v8::Persistent<TypeName>*>(&persistent));
}
I'm new to V8, so I find myself wondering if it's safe or not. Or if it can
be safe in some cases.
