QUESTION
I m a noob in c++ and v8 engine. when I check the source code of the implementation of v8 JSI, I found which I can not understand: Here is the constructor of the v8 runtime: (pls see comments line below)
...ANSWER
Answered 2020-Nov-23 at 10:12context_
is a global handle (v8::Global
), its Reset(...)
method is how you assign to the pointer it wraps. So it's being "reset" from being uninitialized to storing the newly created global context here.
This is probably just defensive programming. – Botje
No, defensive programming has nothing to do with it.
Just treat it as an assignment. – Botje
Yes. If context_
was a v8::Local
(which would be a problem for other reasons), then you'd just see context_ = CreateGlobalContext(...)
here.
