ClassTail : ClassHeritage { ClassBody }
|
|
...
|
|
19. Let F be constructorInfo.[[Closure]].
|
|
20. If ClassHeritage_opt is present and protoParent is not null, then set F.[[ConstructorKind]] to "derived".
|
|
21. Perform MakeConstructor(F, false, proto).
|
|
22. Perform MakeClassConstructor(F).
|
|
...
|
|
33. If PrivateBoundIdentifiers of ClassBody contains a Private Name P such that P's [[Kind]] field is either "method" or "accessor" and P's [[Brand]] is F,
|
|
a. PrivateBrandAdd(F, F).
|
|
...
|
|
|
|
PrivateBrandCheck(O, P)
|
|
1. If O.[[PrivateBrands]] does not contain an entry e such that SameValue(e, P.[[Brand]]) is true,
|
|
a. Throw a TypeError exception.
