|
PrivateFieldGet (P, O)
|
||
|
|
1. Assert: P is a Private Name.
|
||
|
|
2. If O is not an object, throw a TypeError exception.
|
||
|
|
3. If P.[[Kind]] is "field",
|
||
|
|
a. Let entry be PrivateFieldFind(P, O).
|
||
|
|
b. If entry is empty, throw a TypeError exception.
|
||
|
|
c. Return entry.[[PrivateFieldValue]].
|
||
|
|
4. Perform ? PrivateBrandCheck(O, P).
|
||
|
|
5. If P.[[Kind]] is "method",
|
||
|
|
a. Return P.[[Value]].
|
||
|
|
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).
|
||
|
|
|
||
|
|
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.
