|
|
esid: sec-privatefieldget
|
|
info: |
|
|
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).
