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).
|
|
|
|
ClassElementName : PrivateIdentifier
|
|
1. Let privateIdentifier be StringValue of PrivateIdentifier.
|
|
2. Let privateName be NewPrivateName(privateIdentifier).
|
|
3. Let scope be the running execution context's PrivateEnvironment.
|
|
4. Let scopeEnvRec be scope's EnvironmentRecord.
|
|
5. Perform ! scopeEnvRec.InitializeBinding(privateIdentifier, privateName).
|
|
6. Return privateName.
|
|
|
|
MakePrivateReference ( baseValue, privateIdentifier )
|
|
1. Let env be the running execution context's PrivateEnvironment.
|
|
2. Let privateNameBinding be ? ResolveBinding(privateIdentifier, env).
|
|
3. Let privateName be GetValue(privateNameBinding).
|
|
4. Assert: privateName is a Private Name.
|
|
5. Return a value of type Reference whose base value is baseValue, whose referenced name is privateName, whose strict reference flag is true.
