esid: sec-getvalue

|
GetValue(V)
|
|
...
|
|
5. If IsPropertyReference(V), then
|
|
...
|
|
b. If IsPrivateReference(V), then
|
|
i. Let env be the running execution context's PrivateNameEnvironment.
|
|
ii. Let field be ? ResolveBinding(GetReferencedName(V), env).
|
|
iii. Assert: field is a Private Name.
|
|
iv. Return ? PrivateFieldGet(field, base).
|
|
c. Return ? base.[[Get]](GetReferencedName(V), GetThisValue(V)).
|
|
PrivateFieldGet(P, O)
|
|
...
|
|
4. Perform ? PrivateBrandCheck(O, P).
|
|
5. If P.[[Kind]] is "method",
|
|
...
|
|
6. Else,
|
|
a. Assert: P.[[Kind]] is "accessor".
|
|
b. If P does not have a [[Get]] field, throw a TypeError exception.
|
|
c. Let getter be P.[[Get]].
|
|
d. Return ? Call(getter, O).
