PrivateFieldSet (P, O, value )
|
||
|
|
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. Set entry.[[PrivateFieldValue]] to value.
|
||
|
|
d. Return.
|
||
|
|
4. If P.[[Kind]] is "method", throw a TypeError exception.
|
||
|
|
5. Else,
|
||
|
|
a. Assert: P.[[Kind]] is "accessor".
|
||
|
|
b. If O.[[PrivateFieldBrands]] does not contain P.[[Brand]], throw a TypeError exception.
|
||
|
|
c. If P does not have a [[Set]] field, throw a TypeError exception.
|
||
|
|
d. Let setter be P.[[Set]].
|
||
|
|
e. Perform ? Call(setter, O, value).
|
||
|
|
f. Return.
|
||
|
|
|
||
|
|
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.
